It becomes more dense.
It becomes less dense.
It releases energy to the environment.
It absorbs energy from the environment.
It rises upward.
It sinks downward.

Answer 1

For water, as the temperature goes up the density of the liquid water decreases therefore it becomes less dense so it tends to rise upward. And since the temperature here is higher, heat flows from the higher temperature to the lower so it releases energy to the environment. Therefore, the correct statements are 2, 3 and 5.
