Question
An athlete whose mass is 70.0 kg drinks 16.0 ounces (454 g) of refrigerated water. The water is at a temperature of 35.0°F. (a) Ignoring the temperature change of the body that results from the water intake (so that the body is regarded as a reservoir always at 98.6°F), find the entropy increase of the entire system. (b) What If? Assume the entire body is cooled by the drink and the average specific heat of a person is equal to the specific heat of liquid water. Ignoring any other energy transfers by heat and any

- (a)On a winter day, a certain house loses 5.33 10 ✕8J of heat to the outside. What is the total change in entropy of the universe due to this heat transfer alone, assuming an average indoor temperature of 24.0°C and an average outdoor temperature of 5.05°C?(b)This large change in entropy implies a large amount of energy has become unavailable to do work. Where do we find more energy when such energy is lost to us?arrow_forwardA container of ideal gas at standard temperature and pressure (273 K and 1 atm) undergoes an isothermal expansion and its entropy changes by 3.7 J/K. How much work does it do?arrow_forwardA 2.00-mol sample of H2 gas is contained in the left side of the container shown below, which has equal volumes on the left and right. The right side is evacuated. When the valve is opened, the gas streams into the right side. (a) What is the entropy change of the gas? (b) Does the temperature of the gas change? Assume the container is so large that the hydrogen behaves as an ideal gas. (Wouldn't the temperature decrease because the temperature in a vacuum would be really cold?)arrow_forward
