2. Which change in state requires that energy be added to the substance?
a. vaporizing
b. freezing
C. condensing
d. deposition



Answer :

Vaporization is one of the phase transitions that needs additional thermal energy. The kinetic energy of molecules will increase when heat energy is introduced to a substance.

The vaporization of a state?

vaporization is the process by which a substance is transformed from its liquid or solid state into its gaseous (vapour) state. Boiling is the term for the vaporization process when conditions permit the creation of vapour bubbles within a liquid. Sublimation is the process of converting a solid into a vapor.

Does freezing add or subtract energy?

During freezing, a substance's temperature stays constant while the liquid's dissolved particles transform into crystalline solids. Energy is released because particles in a liquid have more energy than particles in a solid.
