D)all of the above
E)none of the above

Question

Quizplus · Accepted Answer

During the process of melting, the energy absorbed by the block of ice is used to overcome the intermolecular forces holding the water molecules in a solid state. This energy is not used to increase the temperature of the ice block, so there is no change in temperature during the melting process. Therefore, choice C is the most accurate answer.

As a Block of Ice at 0°C Melts, the Block
