15 Daily life actions And the Science Behind it..

Shares

You may not believe the concept of gravity, you may think science to be the manipulative reason behind any fact, but you will never forget that it had once spoiled your milk (if it had like me :p)when kept outside in summers and since then till now, you were not given any work.
Whether you love it or not, you can’t escape the fact that science has now became the backbone of technology, without which life is almost nothing now. It has invaded in every branch of modern life and here, I am going to list out some instances where we encounter with science almost daily, but ignore.

1. Ice floats on water

Explanation: Water in its liquid form is more dense than solid (one of the exceptional cases).

2. Harmonious sound from piano

Explanation: Energy conservation law, vibrations in the keys produce sound waves and hence sound.

3. Sounds and Visuals in Television

Explanation: Again energy conservation law, electric energy is being converted to sound and light energy.

4. Washing fruits before eating

Explanation: To wipe off the bacteria present on it.

5. All the food we eat

Explanation: The chemical energy from the food changes to mechanical energy, thermodynamic energy and that every kind of energy body needs to sustain living.

6. To and Fro motion of a swing

Explanation: A swing with its center of gravity at the center points(the one lying nearer to ground) keeps moving to and fro like a pendulum motion.

7. Walking on the road

Explanation: We are able to walk due to the force of friction earth provides in the direction opposite to the motion otherwise the whole scene would be like that of walking on ice.

8. Talking over mobile phone

Explanation: It is the microwaves that travel from one mobile tower to other tower before it reaches you as a sound wave.

9. Cooking food

Explanation: Radiation, Conduction and Convention are a medium for the transfer of heat from stove to food. In microwave, it is Micro waves that heat the food.

10. What makes vehicles run?

Explanation: It is the combustion process of fuels like petrol that provides energy which makes a vehicle move.

11. Use of household appliances like Mixer

Explanation: A mixer uses electrical to produce centrifugal one to turn its blades that chop up the food.

12. Role of medicines in human body

Explanation: Minor problem like cold, cough which are earlier the causes of deaths can now be treated just by having a pill that kills the viruses present once taken.

13. Souring of milk

Explanation: Milk when not kept in refrigerator undergoes fermentation (especially in summers) since the temperature favors bacterial growth that converts milk sugar(lactose) into lactic acid.

Source

14. Rapid cooking in pressure cookers

Explanation: Cooking in presence increased pressure decreases the boiling point of food inside the container, that makes the required food rapidly and with less usage of fuel.

Source

15. Falling in LOVE

Explanation: It is chemical named ‘Dopamine’ that is created in the brain when one falls in love that affects various organs like genitals, sweat glands, senses and enhances the release of testosterone.

No, the list is not that short, but it was designed for you to start realizing the sciences behind every thing you use, every action of yours, every sound and everything that surrounds you. Find them out, share with us!
