Write down the definitions of the following 1. Evaporation
2. Transpiration 3. Photosynthesis
4. Condensation 5. Irreversible change
Answers
Evaporation:-
Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure. Evaporation is a fundamental part of the water cycle and is constantly occurring throughout nature.
Transpiration:-
Transpiration is the evaporation of water from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis. ... This transpired water must be replaced by the transport of more water from the soil to the leaves through the xylem of the roots and stem.
Photosynthesis:-
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.
Condensation:-
Condensation has multiple meanings in the field of biology. A condensation reaction is when two smaller molecules join to form a larger one by removing functional groups that form a small molecule, often water.
Irreversible Change:-
Irreversible changes. A change is called irreversible if it cannot be changed back again. In an irreversible change, new materials are always formed.

Explanation:
1.Evaporation: process of turning of a liquid into gas.
2.Transpiration: This process of elimination of excess water from the plant body is known as transpiration.
3.Photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.
formula: The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen
4.Condensation: Condensation is the change of the physical state of matter from the gas phase into the liquid phase, and is the reverse of vaporization.
5.Irreversible change: Irreversible changes. A change is called irreversible if it cannot be changed back again.
In an irreversible change, new materials are always formed. Sometimes these new materials are useful to us.
example: burning, etc.
