What happens to energy during a change of state? Why is it a physical change?​
Flura [38]

Answer & Explanation:

Energy is heat. For example, if you boil a cup of water it has more energy than   a cup at room temperature. It is considered a physical change because its properties do not change only the state of matter. On the other hand, if wood burns then that is a chemical change because it changes its chemical properties. Please rank as Brainliest if this helps! Thank you!
