1.)   If 980 kJ of energy as heat are transferred to 6.2 L of water at 291 K, what will the final temperature of the water be? The specific heat of water is 4.18 J/g * K. Assume that 1.0 mL of water equals 1.0 g of water.

Cp=   q                                           Cp=specific heat at a given pressure
     ----------                                       m= mass    q=energy transfered as heat
      m(temp final - time temp)

2.) How much energy as heat must be transferred to raise the temperature of a 55 g sample of aluminum from 22.4 degrees C to 94.6 degrees C ? The specific heat of aluminum is 0.897 J/g*K. Note that a temperature change of 1 degree C is the same as a temperature change of 1 K because the sizes of the degree divisions on bothe scales are equal.
