Your sister, who is a realtor, is quite interested in your studies in physics. Part of her job in selling properties involves being aware of the details of heating systems for the houses. She comes to you one day and says that a client told her the following: “If you measure the internal energy in the air in a houseand then turn up the thermostat to a higher temperature, the internal energy of the air in the house is exactly the same as it was at the lower temperature.” She finds this hard to believe, since you have added energy to the air by running the furnace. Help her to figure out if this statement is true or not.

Why is a person able to remove a piece of dry aluminum foil from a hot oven with bare fingers, whereas a burn results if there is moisture on the foil?
On his honeymoon, James Joule traveled from England to Switzerland. He attempted to verify his idea of the inter-convertibility of mechanical energy and internal energy by measuring the increase in temperature of water that fell in a waterfall. For the waterfall near Chamonix in the French Alps, which has a 120-m drop, what maximum temperature rise could Joule expect? He did not succeed in measuring it, partly because evaporation cooled the falling water and also because his thermometer was not sufficiently sensitive.
An aluminum rod 0.500 m in length and with a cross-sectional area of 2.50 cm2 is inserted into a thermally insulated vessel containing liquid helium at 4.20 K. The rod is initially at 300 K. (a) If one-half of the rod is inserted into the helium, how many liters of helium boil off by the time the inserted half cools to 4.20 K? Assume the upper half does not yet cool. (b) If the circular surface of the upper end of the rod is maintained at 300 K, what is the approximate boil-off rate of liquid helium in liters per second after the lower half has reached 4.20 K? (Aluminum has thermal conductivity of 3 100 W/m K at 4.20 K; ignore its temperature variation. The density of liquid helium is 125 kg/m3.)
When a gas undergoes an adiabatic expansion, which of the following statements is true? (a) The temperature of the gas does not change. (b) No work is done by the gas. (c) No energy is transferred to the gas by heat. (d) The internal energy of the gas does not change. (e) The pressure increases.
If a gas is compressed isothermally, which of the following statements is true? (a) Energy is transferred into the gas by heat. (b) No work is done on the gas. (c) The temperature of the gas increases. (d) The internal energy of the gas remains constant. (e) None of those statements is true.
In the heating seasons the heat loss from a building (and thus the heating cost) is strongly dependent on the difference between the indoor and outdoor temperature. If the average outdoor temperature in a particular city during the heating season is 45 F (7 C), what is the effect on heating cost percentage-wise if the thermostat setting is fixed at 74 F (23.3 F) instead of 68 F (20 C)?
One gram of water (1 cm3) becomes 875 cm3 of steam when boiled at a constant pressure of 1 atm (1.013 x 105 Pa). The heat of vaporization at this pressure is Lv = 2.256 x 106 J/kg. Compute a) the heat absorbed by the water b) the work done by the water when it vaporizes and c) its increase in internal energy.
To illustrate the effect of ice on the aluminum cooling plate, consider the drawing shown here and the data that it contains. Ignore any limitaions due to significant figures. How much heat per second per square meter is conducted through the ice-aluminum combination and through the aluminum by itself? combination: 6580 J/(s m2), aluminum only: 6580 J/(s m2) combination: 2400000 J/(s m2), aluminum only: 2400000 J/(s m2) combination: 2400000 J/(s m2), aluminum only: 6580 J/(s m2) combination: 6580 J/(s m2), aluminum only: 2400000 J/(s m2)
What is the change in internal energy (in J) of a system that does 4.50 ✕ 105 J of work while 3.40 ✕ 106 J of heat transfer occurs into the system, and 9.00 ✕ 106 J of heat transfer occurs to the environment?
Consider a room that is initially at the outdoor temperature of 20 C. The room contains a 60-W light bulb, a 3000-W electric oven, a 400-W TV set and two 300-W fridge. Assuming no heat transfer through the walls, determine the rate of increase of the energy content of the room when all of these electric devices are on.
A 75-kg cross-country skier glides over snow as in Figure P11.33. The coefficient of friction between skis and snow is 0.20. Assume all the snow beneath her skis is at 0°C and that all the internal energy generated by friction is added to snow, which sticks to her skis until it melts. How far would she have to ski to melt 1.0 kg of snow?
