How much heat(energy) in calories will it take to warm 25 g of ice at 10 degrees C to liquid water at 40 degrees C?

q1 = heat to warm ice from 10 to zero degrees C (without melting it).
q1 = mass ice x specific heat ice x delta T (delta T is 10).
q2 = heat to melt ice at zero degrees C.
q2 = mass ice x heat fusion.
q3 = heat to raise temperature of water zero C to +40.
q3 = mass water x specific heat water x delta T.
Total heat energy is q1 + q2 + q3.
You will need to look up specific heat ice, specific heat water and heat fusion of water.Post your work if you get stuck.
q2 =
