What is the heat given to or given up by a substance while changing state?
AI Explanation
The correct answer is B) latent heat.
Latent heat is the heat given to or given up by a substance during a change of state, such as from liquid to gas (vaporization) or from gas to liquid (condensation). This heat is used to overcome the intermolecular forces that hold the molecules of a substance together in a particular state, without causing a change in the substance's temperature.
The other options are incorrect because they refer to specific phase changes rather than the heat involved in those changes. Condensation and vaporization are the processes of changing state, while evaporation and condensation are the terms used to describe the heat transfer during those processes.
