A gas in a cylinder expands from a volume of 0.100 m³ to 0.330 m3 . 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.

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

A cylinder contains 0.250 mol of carbon dioxide (CO₂) gas at a temperature of 27.0°C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1.00 atm on the gas. The gas is heated until its temperature increases to 127.0°C. Assume that the CO₂ may be treated as an ideal gas. Part A How much work is done by the gas in this process?
