Amazing Chemistry Facts In Day To Day Life

Water is a unique substance: Water is essential for life and has several remarkable properties. It has a high specific heat capacity, which means it can absorb a lot of heat before its temperature changes. This property helps regulate Earth's temperature and keeps aquatic environments stable.
Chemical reactions in cooking: When you cook, various chemical reactions occur that transform the ingredients. For example, caramelization is a reaction that occurs when sugar is heated, resulting in the characteristic browning and flavor development in foods like caramel and roasted vegetables.
Acid-base reactions: Acid-base reactions are common in daily life. For instance, the fizzing sensation you experience, when you mix baking soda and vinegar, is due to the reaction between the acidic vinegar and the basic baking soda, resulting in the production of carbon dioxide gas.
Food preservation: Chemistry plays a crucial role in food preservation techniques. Processes like pickling, salting, and canning rely on chemical reactions to inhibit the growth of microorganisms and extend the shelf life of food.
pH and cleaning products: pH is a measure of acidity or alkalinity. Many cleaning products, such as detergents and soaps, are formulated to have specific pH levels for optimal cleaning. For example, alkaline cleaning agents are effective in removing grease and oils, while acidic cleaners can dissolve mineral deposits.
Medicinal chemistry: Medicinal chemistry focuses on the design and development of drugs. Many life-saving medications, such as antibiotics, painkillers, and antiviral drugs, are the result of extensive chemical research and understanding of how molecules interact with biological systems.
Chemical reactions in batteries: Batteries power many of our devices, and they rely on chemical reactions to produce electricity. For example, in a typical alkaline battery, a chemical reaction occurs between the zinc anode and manganese dioxide cathode, allowing the flow of electrons and generating electrical energy.
Natural dyes: The vibrant colors in fruits, flowers, and other natural materials are often the result of complex organic molecules called pigments. These pigments, such as chlorophyll (green) and anthocyanins (red, purple, and blue), exhibit fascinating chemical structures and properties.
Fireworks and pyrotechnics: Fireworks displays are a spectacular example of chemistry in action. Different metal salts are used to produce colorful explosions and vibrant displays. Each color corresponds to a specific metal ion that emits characteristic wavelengths of light when heated.
The chemistry of fragrance: Perfumes and fragrances contain a variety of chemical compounds that produce specific scents. Essential oils, for example, contain volatile aromatic compounds that evaporate easily and release pleasant odors.

Best Basic Chemistry Formulas To Learn

Density: Density is the mass of a substance per unit volume. The formula for density is:Density = Mass / Volume
Molar Mass: Molar mass is the mass of one mole of a substance. It is calculated by summing the atomic masses of all the atoms in the chemical formula. The formula for molar mass is:Molar Mass = (Mass of Element 1 × Number of Atoms of Element 1) + (Mass of Element 2 × Number of Atoms of Element 2) + ...
Percent Composition: Percent composition gives the relative mass percentage of each element in a compound. The formula for percent composition is:Percent Composition of Element = (Mass of Element / Molar Mass of Compound) × 100%
Stoichiometry: Stoichiometry deals with the quantitative relationships between reactants and products in a chemical reaction. The balanced chemical equation provides the basis for stoichiometric calculations.Example: In the balanced equation: 2H₂ + O₂ → 2H₂O, it shows that 2 moles of hydrogen react with 1 mole of oxygen to produce 2 moles of water.
Gas Laws:
- Boyle's Law: The pressure and volume of a gas are inversely proportional at constant temperature. The formula for Boyle's Law is:P₁V₁ = P₂V₂
- Charles's Law: The volume and temperature of a gas are directly proportional at constant pressure. The formula for Charles's Law is:V₁ / T₁ = V₂ / T₂
- Avogadro's Law: The volume and the number of moles of a gas are directly proportional at constant temperature and pressure. The formula for Avogadro's Law is:V₁ / n₁ = V₂ / n₂
- Ideal Gas Law: The ideal gas law relates the pressure, volume, number of moles, and temperature of a gas. The formula for the ideal gas law is:PV = nRTwhere P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

Fun Chemistry Facts 101

Even though most people limit chemistry as a science subject that is dull and full of equations and numbers, there is a long list of fun chemistry facts 101 that prove that chemistry is not as boring as it is assumed to be. If you do not believe it, let us discuss some of the top fun facts of chemistry below-

The first and the most intriguing factor about chemistry is that as opposed to other substances available that reduce in size when frozen, water or H2O is the only substance that instead expands in size after freezing.
Did you know that a glass substance can either be classified as a liquid or a solid? Instead, according to chemists, glass is considered to be somewhere between a solid and a liquid.
You all know that our body has hydrogen atoms. But, did you know that each hydrogen atom in our body is approximately 13 billion years old? This is because they were all created at the same time that the universe was given birth.
Everyone knows about gravity and how it functions, however, did you know that there exists a particular property in liquid helium that defies gravity and instead goes the other way? According to chemists, liquid helium at a temperature very close to 0 becomes zero viscosity fluid which can then move in any direction.
Another unique fact about chemistry is that if you take a glass of water and add a handful of salt into it, the level of water will go down as the volume of salt or sodium chloride reduces the volume of water in the glass.

Tips To Study Chemistry Better

Along with chemistry tuition, there are multiple other ways that you can incorporate in your learning and study schedule to make the best use of your time to study chemistry more efficiently. These tips and tricks do not require a lot of effort and time but the results will always be in your favour.

So, how to study chemistry? Let us discuss some quick tips to study chemistry more effectively below-

The first step to studying chemistry properly is to always study and review all the class material available on a particular topic before you go for the class. This is important as this will give you ample time to grasp the basics of the topic, which will reduce the time you take during class to understand the intricacies involved around the same.
Always begin to study chemistry by building up a strong foundation. This is only possible if you first gain ample knowledge and understanding of the concepts that are fundamental to the subject. Do not rush and try to learn more than you can take under peer pressure. Take it slow, starting right from the basics.
Very few people understand the importance of taking the right notes during each class but at the end of the day, having revision or review notes for each chemistry session during school hours can evidently improve your learning ability along with knowledge on the subject.
Along with theory, improving your practical knowledge about chemistry lessons is highly crucial to succeed in this subject. In order to gain practical knowledge, attending and participating in all lab sessions is a must.
Lastly, every time you begin a new chapter or topic, always make a mind map of the different topics that are included and tick of each topic that you cover. This practice is not only successful in pacing up your learning, but it also is a motivating activity as the more topics you tick off, the more accomplished you feel.

Overall, to conclude, no matter the level of chemistry you studied as a student or during your undergraduate year at university, there are multiple other chemistry courses available in and around you, especially online, for you to get an in-depth understanding of organic chemistry along with organic synthesis.

Most of these courses are conducted in the English language and outside the academy, cure to allow not only the local undergraduate students but also international students to come and explore a range of chemistry courses to increase their research skills and credits where possible.

If you are someone who is looking to increase their level of chemistry understanding, sign up with Superprof today and increase your independent study hours with the best level of chemistry tuition available for you.
