7. A bottle containing 740 g of liquid water was removed from a cooler at a temperature of 1.2 °C and placed on a picnic table on a warm day. The water sat on the table for several hours and eventually reached a temperature of 29 °C. The specific heat of water is 4186 J/(kg · °C).
a) How much heat was transferred from the surroundings to the water during this time?
b) If the same amount of heat had been used to melt an ice cube at a temperature of 0 °C, what would be the mass of ice that it could melt? (The latent heat of fusion coefficient for water is 3.34 × 105 J/kg.)
