It is difficult to extinguish a fire on a crude oil tanker, because each liter of crude oil releases 2.80 x 107 J of energy when burned. To illustrate this difficulty, calculate the number of liters of water that must be expended to absorb the energy released by burning 1.00 L of crude oil, if the water has its temperature raised from 17.5 °C to 100 °C, it boils, and the resulting steam is raised to 315 °C. Use 4186 J/(kg-°C) for the specific heat of water and 2020 J(kg.°C) for the specific heat of steam. amount of water:

Suppose that on a dry, sunny day when the air temperature is near 37°C, a certain swimming pool would increase in temperature by 1.15°C in one hour if not for evaporation. What fraction of the water in the pool must evaporate during this time to carry away precisely enough energy to keep the temperature of the pool constant? The specific heat of water is 4186 J/(kg- °C). At 37°C, the latent heat of vaporization of water is 2430 kJ/kg. Assume that the water in the pool is close enough to 37 °C that this value for the latent heat can be used. mass ratio of evaporated water:
