PLEASEEE HELPPPPP
Melting 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.

Hi my dear friend,

Because we must add heat, boiling water is a process that chemists call endothermic. Clearly, if some processes require heat, others must give off heat when they take place. ... Changes of state involve a solid melting, a liquid freezing, a liquid boiling or a gas condensing.

~Thank you
When you boil it you increase the temperature or how fast the molecules move
