1) The temperature of 550 g of water is changed from 20.8*C to 25.3*C. How much heat did this sample absorb?

2) How much heat in kilojoules has to be removed from 733 grams of water to lower its temperature from 22*C to 9*C?

3) To bring 1.5 Kg water from 31*C to 102*C takes how much heat input?

4) A sample of copper (specific heat capacity of copper is 0.386J/g*C) absorbs 1200 J of heat and the temperature of the water it is being heated in increases from 27*C to 95*C, what mass of copper was heated?

5) What will be the change in temperature if 600 g of water absorbs 5200 J of heat?

6) What will be the final temperature of a sample of water, if 32 kJ of heat is removed to lower 836 g of water starting with an initial water temperature of 25*C?

7) What is the specific heat of aluminum if it takes 205 J to raise the temperature of 20.7 grams of Al 11.0*C?

8) An insulated cup contains 67 g of water at 21*C. A 34 g sample of metal a5 73*C is added. The final temperature of the water is 26*C. What is the specific heat capacity of the metal?

9) A sample of metal with a specific heat capacity of 067J/g*C is heated to 90*C and then placed on a .123 kg sample of water at 26*C. When equilibrium is reached, the final temperature of the water is 39*C. What was the mass of the metal?

10) A 40 gram block of copper at 95*C is placed in 105 g of water at an unknown temperature. After equilibrium is reached, the final temperature of the water is 24*C. What was the initial temperature of the water?
