Question

Describe how the science of Chemistry contributes to your everyday life.

Answer 1

Chemistry is in everday life.

We cannot live without chemistry. Let us see how

1) The only source of energy for earth is Sun, which emits radiation being absrobed by plants.

Plants use this energy for production of O2 due ot presence of chlorophyll. Chlorophyll is a pigment which absorb energy due to its chemical structure.

2) the photosynthesis is a chemical reaction

6CO2 + 6H2O --> C6H12O6 + 6O2

3) the use of oxygen by us is through respiration is a chemical reaction again

C6H12O6 + 6O2 --> 6CO2 + 6H2O + liberation of energy

4) the food we eat is digested by enzymatic action (again a chemical reaction)

5) The water we drink gives us minerals (ions dissolved in water)

6) Everything is made up of chemicals

7) the boiling of water at different pressure is different at differnt temperature ( colligative property , Rault's law)

8) Our emotions are even controlled by release of chemicals in our body (hormones)
