you take 250.0 g of ice from the refrigerator at -8.00 degrees celsius. how much heat does it take to warm it to room temperature, 20.0 degrees celsius?
add the following:
heat ice to zero
melt ice at zero
heat water from zero to 20C
if you get really lazy you can always use calories (1 small calorie=the energy to increase 1 gram of water by 1 degree Celsius)
Think why that wont work, Jay: We are dealing with ice, then ice melting at constant temperature, then for the lazy, heating water.
