Homework Help: physic

a resistor has a voltage of 6.65 V and a current of 4.45 A. it is placed in a calorimeter containing 200g of water at 24 degree Celsius. the calorimeter is aluminum (specific heat= 0.220 cal/g-Celsius), and its mass is 60g. the heat capacity of the resistor itself is negligible. what is the temperature of the system 500 s later if all the electrical energy goes into heating the water and the calorimeter?

Please show me steps. The lab shows some equations i can use, but I do not fully understad.
