Asked by Mary
Suppose you have a 50.0g sample of ice at -30.0 C. How many joules of heat energy are needed to heat the ice to 0.0 C? How many joules of heat energy are needed to melt the ice? I do not know how to set either of these up.

50 g sample of ice.
-30 C initial T
0 C final T
q = mass ice x specific heat solid ice x (Tfinal-Tinitial) = ?
To melt the ice at zero to water at zero.
q = mass ice x heat fusion ice = ?
