HEY MATE HERE IS YOUR ANSWER--
ACTIVITY
The soil in natural state contains lots of moisture that helps in the growth of the plants. This theory can be easily proved by taking some soil in a test tube and heat it to a high temperature.
Gradually, the water vapor arises up the test tube and reaches to colder topmost part of the test tube, where the these vapors may condense due to the touch of the colder surface, if the test tube is closed, thus proving the existence of water in the soil.
If the test tube is open, the water vapors escape out in the atmosphere and if the soil is weighed before and after the heating, the difference in weight proves that soil contains water.
