If a 0.250g of fuel increases the temperature of a calorimeter by 20* C, and the calorimeter is calibrated at 7.28 kJ/*C, calculate the heat of combustion of fuel per gram. Show your work.

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.
