A 74.2 g sample of an unknown substance experiences a temperature change of 8.63 °C while absorbing 736.8 joules of heat. What is the specific heat capacity of this substance? Equation: q=mCΔT

Cwater = 4.18 J/goC

Cwater = 1.00 cal/goC

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.
