During which phase change will two grams of water

release 668 joules of heat energy?

A. melting

B.

freezing

C.

vaporization

D. condensation

Answers

Answer 1
D would be the best answer is this situation so yeah thank me later
Answer 2

During the phase change of 2 grams water to solid-state, there has been the release of energy, and the process will be freezing. Thus option B is correct.

The release of the amount of heat by the sample has been able to change the state of the matter from the loosely bounded to the combat state.

The melting has been the process of conversion of solid-state to a liquid state. In the process, there has been the absorption of the energy for the rupture of the bond.

The freezing has been the conversion of liquid state to solid-state. The process requires a little amount of energy for the conversion.

The vaporization requires the absorption of energy and converts the liquid state to the vapor state.

The condensation has been the process of conversion of the vapor to the gaseous state. The process releases energy in large amounts.

Thus, during the phase change of 2 grams water to solid-state, there has been the release of energy, and the process will be freezing. Thus option B is correct.
