1. If 121.4 kJ of heat are added to 6.10 × 102 g of water at 22.0°C, what is the final temperature of the water? Specific heat of water at 1.00 atm and 20.0°C is 4.186 kJ/kg·K. (Refer to Table 14.1.)

2. It takes 880 J to raise the temperature of 350 g of lead from 0°C to 20.0°C. What is the specific heat of lead?

3. A 4.00-kg steel ball at 27.3°C is dropped from a height of 10.8 m into an insulated container with 4.50 L of water at 10.1°C. If no water splashes, what is the final temperature of the water and steel? The specific heat of steel and water is 450 J/(kg·K) and 4186 J/(kg·K)
