What is common between melting and evaporation?
they either take away heat or heat is added.
Is heat taken away or added in evaporation?
Taken away. As a liquid evaporates, it loses heat to the atmosphere.
Is heat energy being added or removed during boiling?
added
How does evaporation change from a liquid to a solid?
It doesn't. Evaporation is the change of state from a liquid to a gas, caused by added surface heat. You're thinking of freezing, caused by loss of heat.

Is evaporating a physical change?
Yes. Evaporation is a physical change of state. In the case of evaporation enough heat, called the Latent Heat of Vaporization, is added to a liquid to change it from liquid to gas.
Why object coll when heat is removed?
Because the object becomes hot when heat is added.
What is the being added or removed when a substance temperature changes?
