Identify the arrows that show removal of thermal energy when matter changes state.

Hello,

Looking at the picture you can tell that the arrows pointing to the left identify the release of thermal energy. So, we can eliminate those arrows being potential answers for this question. Next, we look at the arrows pointing to the right. Seeing as it goes from solid to a liquid to a gas, we can see that the arrows pointing to the right show the removal of thermal energy. So you should click all the arrows pointing to the right.

Hope this helps!!
