A 1.0 kg glass bowl at 37 °C is placed in a freezer. How much heat will the freezer have to remove from the bowl to take it to 0 °C? (cglass = 0.2 cal/deg-gm)
Q (heat) = M * C *(change in T)
M is the mass and C is the specific heat. You know all three quantitiies
Take it from there.
Would the change be a negative number?
Calculate the amount of heat required to heat a 45 sample of ethanol from 11.0 to 19.0. Specific heat capacity of ethanol is 2.42 .
