Step 1
Does heat have to be added to or removed from solid ice at 0 °C?
Answer
Heat must be added to solid ice at 0 °C to change its state to liquid water at the same temperature. This process is known as fusion, where ice transitions to water while both are at the same temperature of 0 °C.
To facilitate this state change, energy is required to overcome the intermolecular forces holding the ice molecules in a rigid structure. This energy is referred to as latent heat. It is essential to provide enough energy to break these forces so that the structure of the solid ice can transition into the more fluid structure of liquid water. Therefore, the correct response is that heat must be added to the ice.
