One of a dilute diatomic gas occupying a volume of 10.00 L expands against a constant pressure of 2.000 atm when it is slowly heated. If the temperature of the gas rises by 10.00 K and 400.0 J of heat are added in the process, what is its final volume?
In an air conditioner, 12.65 MJ of heat transfer occurs from a cold environment in 1.00 h. (a) What mass of ice melting would involve the same heat transfer? (b) How many hours of operation would be equivalent to melting 900 kg ofice? (c) If ice costs 20 cents per kg, do you think the air conditioner could be operated more cheaply than by simply using ice? Describe in detail how you evaluate the relative costs.
If the air temperature isthe same as the temperature of your skin (about 30°C), your body cannotget rid of heat by transferring it to the air. In that case, it gets ridof the heat by evaporating water (sweat). During bicycling, a typical70 kg person’s body produces energy at a rate of about 500 W due tometabolism, 80% of which is converted to heat. (a) How many kilogramsof water must the person’s body evaporate in an hour to get ridof this heat? The heat of vaporization of water at body temperature is2.42 * 10^6 J/kg. (b) The evaporated water must, of course, be replenished,or the person will dehydrate. How many 750 mL bottles of watermust the bicyclist drink per hour to replenish the lost water? (Recall thatthe mass of a liter of water is 1.0 kg.)
Suppose 8.50 x 10° J of energy are transferred to 1.79 kg of ice at 0°C.

(Enter your answer to at least three significant figures.) (b) How much energy (in J) remains to raise the temperature of the liquid water? (Enter your answer to at least three significant figures.) (c) Determine the final temperature of the liquid water in Celsius. °C

Calculate how many kg an 80 kg person who replaces 30 minutes/day will lose in a yearin front of the TV for 30 minutes of brisk walking. Use the following data: Expensecalories during the walk (5 km/h) = 0.063 kcal/kg/minute. Calorie expenditure watching TV = 0.028kcal/kg/min. 1 kg of weight lost is equivalent to about 7000 kcal.
Digestingfat produces 9.3 food calories per gram of fat, and typically 80%of this energy goes to heat when metabolized. (One food calorie is1000 calories and therefore equals 4186 J.) The body then movesall this heat to the surface by a combination of thermal conductivityand motion of the blood. The internal temperature of the body(where digestion occurs) is normally 37C, and the surface is usuallyabout 30C. By how much do the digestion and metabolism of a2.50 g pat of butter change your body’s entropy? Does it increase ordecrease?
