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
A 68 kg cyclist is pedaling down the road at 15 km/h, using a total metabolic power of 480 W. A certain fraction of this energy is used to move the bicycle forward, but the balance ends up as thermal energy in his body, which he must get rid of to keep cool. On a very warm day, conduction, convection, and radiation transfer little energy, and so he does this by perspiring, with the evaporation of water taking away the excess thermal energy.
To keep from overheating, the cyclist must get rid of the excess thermal energy generated in his body. If he cycles at this rate for 2 hours, how many liters of water must he perspire, to the nearest 0.1 liter?A. 0.4 L B. 0.9 L C. 1.1 L D. 1.4 L
A 220-lb athlete drinks a glass of soda (125 calories) and walks up to the top of a Library Building. What is the change in his internal energy, assuming the only heat transfer is the 125 calories from the soda drink, and the only work done by the athlete is lifting his own weight to the 6th floor? Assume 3m per floor.
