Changing the state of matter from gas to liquid requires a gain in thermal energy. True or false

False.

Explanation:

Since thermal means heat, then this statement is false.

You would need to cool the gas (or lose thermal energy) for a gas to become a liquid.

To go from a liquid to a gas, then you would apply thermal energy (or the liquid would have to gain thermal energy).

the endocrine system secretes hormones into blood and other body fluids. these chemicals are important for metabolism, growth, water and mineral balance, and the response to stress. hormones provide feedback to the brain to affect neural processing. reproductive hormones affect the development of the nervous system.
