12 of 13 A gas in a cylinder expands from a volume of 0.100 m³ to 0.330 m . Heat flows into the gas just rapidly enough to keep the pressure constant at 1.90x105 Pa during the expansion. The total heat added is 1.20x105 J . For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Thermodynamics of boiling water. Part A Find the work done by the gas. Express your answer in joules. ? W J Submit Request Answer Part B Find the change in internal energy of the gas.
A crate of fruit with a mass of 40.0 kg and a specific heat capacity of 3550 J/(kg. K) slides 9.00 m down a ramp inclined at an angle of 40.0 degrees below the horizontal. Part A If the crate was at rest at the top of the incline and has a speed of 2.55 m/s at the bottom, how much work Wf was done on the crate by friction? Use 9.81 m/s² for the acceleration due to gravity and express your answer in joules. ► View Available Hint(s) Wf = -2140 J Submit Correct The frictional force opposes the motion of the crate, so the work done on the crate by friction must be a negative quantity. Part B Previous Answers If an amount of heat equal to the magnitude of the work done by friction is absorbed by the crate of fruit and the fruit reaches a uniform final temperature, what is its temperature change AT? ► View Available Hint(s) AT = ΑΣΦ W

The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 68 kg (150 lb) person of height 1.83 m (6.0 ft) would have a body surface area of approximately 1.9 m². Part A What is the net amount of heat this person could radiate per second into a room at 19.0° C (about 66.2°F) if his skin's surface temperature is 31.0° C? (At such temperatures, nearly all the heat is infrared radiation, for which the body's emissivity is 1.0, regardless of the amount of pigment.) Express your answer in watts. ΑΣφ ?
