A 75 kg person cannot go out for a long time due to Covid-19 restrictions. That's why he rides a bike at home to keep his weight stable. During bicycling, his body produces energy at a rate of about 450 W due to metabolism, 80% of which is converted to heat. The person's body gets rid of all this heat by evaporating water (sweat). How many grams of water must the person's body evaporate in an hour? The heat of vaporization of water at body temperature is 2.42 x 10^6 J/kg.

Suppose that you have left a 200 mL cup of coffee sitting until it has cooled to 30◦ C, which you find totally unacceptable. Your microwave oven draws 1100W of electrical power when it is running. If it takes 45s for this microwave oven to raise the temperature of the coffee to 60◦ C, what is the efficiency of heating with this oven? You will need to use the fact that 4.2 J of energy is required to raise the temperature of 1.0 mL of coffee by 1.0◦ C.
The urban heat island effect is often strongest at night when temperatures would typically drop. What does this indicate about energy transfer and the material used in the building? (a) The material in buildings releases more energy at night than it absorbs during the day (b) The material in buildings absorbs a lot of energy during the day and when it gets colder at night the energy is released back into the cooler air. (c) The material in buildings absorbs energy during the day and releases it because the temperature of the buildings is lower than the cooler air (d) The material in buildings releases a lot of energy into the hot air during the day so at night all of the energy is still there
8.8 J of work expands an ideal gas in a metal piston cylinder in a bucket of ice water from 3.7 cubic centimeters to 9.9 cubic centimeters. How much heat was transferred from the ice water to the gas? If you feel this question is incomplete, please explain HOW it is incomplete.
The water in a deep underground well is used as the cold resevoir of a Carnot heat pump that maintains the temperature of a house at 303 K. To deposit 13000 J of heat in the house, the heat pump requires 716 J of work. Determine the temperature of the well water.
Two distinct systems have the same amount of stored internal energy. Assume 500 J are added by heat to the first system, and 300 J are added by heat to the second system. What will be the change in internal energy of the first system if it does 200 J of work? How much work will the second system have to do in order to have the same internal energy?
A certain sandwich cookie contains 55 CC of nutritional energy. For what amount of time must you swim in order to work off three cookies if swimming consumes 510 C/hC/h AND Instead of swimming you decide to run for 40 min at a pace that works off 860 C/hC/h. How many cookies have you worked off?
After eating a 200 g pottle of yoghurt, a person decides to go for a run to burn off the extra energy. The yoghurt provides 5.4 MJ kg−1, and he is able to raise his metabolic rate to 220W while running. How long does he have to run?
A 54-kg mountain climber, starting from rest, climbs a vertical distance of 779 m. At the top, she is again at rest. In the process, her body generates 4.4 × 106 J of energy via metabolic processes. In fact, her body acts like a heat engine, the efficiency of which is given by Equation 15.11 as e = |W|/|QH|, where |W| is the magnitude of the work she does and |QH| is the magnitude of the input heat. Find her efficiency as a heat engine.
You put heat energy into your car and it does not work . The difference between what you put in and the work it does is the change in internal energy of your car's "system." This is an example of which law of thermodynamics?

SANAE IV, a research station of The South African National Antarctic Programme (SANAP), is located on Vesleskarvet, Queen Maud Land. It uses an underground lake as the cold reservoir of a Carnot heat pump that maintains the temperature of a science lab at 302.8 K. To deposit 13488 J of heat in the lab, the heat pump requires 1022 J of work. Determine the temperature of water in the underground lake, in Kelvin
The Mach 5 racer driven by Speed Racer has an engine that pulls 14250J of heat energy from a high temperature reservoir held at 1069°C to do 2985J of usable work. a) What is the efficiency of the Mach 5’s engine? b) If the ideal efficiency of the heat engine is 0.675, what is the temperature of the low temperature reservoir in degrees Kelvin?
