At 1 atmosphere of pressure, 15.5 g of a compound at its normal boiling point are converted to a gas by the addition of 34,400 J. What is the heat of
vaporization of this substance? *

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.
