No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
Is evaporated gasoline a chemical change?
No, it would be a physical change. During a chemical change, substance(s) are changed into different substances. An example of a chemical change would be the rusting of iron but a physical change would be freezing water; or in this case, evaporation.

How can you tell the difference between a chemical change and physical change in matter?
You can tell a chemical and a physical change apart because a physical change is any change in size, shape, form, or state where identity of the matter stays the same.Example of a physical: If you cut a watermelon into chunks, the watermelon has changed size and shape.If you put one of the chunks into your mouth and bite it you have changed the size and shape again.Chemical change occurs when one type of matter changes with different properties chemical change goes around you everyday.Signs of a chemical change are the formation of a gas.yes because i wrote it!
What is the total of original and new substances that are the same after a chemical change?
