Astudent heats a liquid on a burner. what happens to the portion of liquid that first begins to warm? what all applys
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.

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.

Good moring let me you on this question the answer the electric force  have a good day ; )
