One mole of water vapor at 346 K cools to 280 K. The heat given off by the cooling water vapor is absorbed by 10 mol of an ideal gas, and this heat absorption causes the gas to expand at a constant temperature of 273 K. If the final volume of the ideal gas is 24 L, determine its initial volume. The specific heat of water is 4186 J/kg °C and the latent heat of vaporization is 2.26 x 106 J/kg. Answer in units of 1.
In a solar water heater, energy from the Sun is gathered by water that circulates through tubes in a rooftop collector. The solar radiation enters the collector through a transparent cover and warms the water in the tubes; this water is pumped into a holding tank. Assume that the efficiency of the overall system is 12.0% (that is, 88% of the incident solar energy is lost from the system). What collector area is necessary to raise the temperature of 450 L of water in the tank from 19°C to 36°C in 2.5 h when the intensity of incident sunlight is 480 W/m2?
