1. A 1.00 kg block of ice at 0 °C is added to a picnic cooler. How much heat will the ice remove as its melts to water at 0 °C? (For this problem, base your significant figures of your answer strictly on the 1.00 kg. You can assume that 0 degrees is an exact measurement and can have as many significant figures as needed.)

2. A heat engine converts 100.0 cal from a supply of 400.0 cal into work. How much mechanical work was done?
