Question

Freezing and Boiling are endothermic processes. This means that these processes absorb energy from their surroundings in order to occur. Use this information and the data you collected in the Phase Change Gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Answer 1

Hi my dear friend,

Changes of state involve a solid melting, a liquid freezing, a liquid boiling or a gas condensing. When steam, which is gaseous water, condenses, heat is released. Likewise when liquid water freezes, heat is given off. In fact heat must be continually removed from the freezing water or the freezing process will stop.
