At the microscopic level heat conduction is a chain of collisions by particles of different kinetic energies. Suppose a heat interaction occurs between a hot object of 80 °C and a cool object of 10 °C, and the primary energy transfer mechanism is heat conduction. If the interaction continues long enough, how will the average kinetic energy of the particles in the (initially) hot object compare to the average kinetic energy of the particles in the (initially) cool object? a. The average KE of the hot object particles will be greater than the average KE of the cool object particles. b. The average KE of the hot object particles will be the same as the average KE of the cool object particles. c. There is no way to determine the correct answer.

4. Ideal Gas Type Question: A piston comprises two nested cylinders which are 3 cm and 2.8 cm in diameter with 0.1 cm thick walls and are each 1 m long. Initially, the smaller cylinder sits completely inside the larger cylinder and is filled with N2 at 20 °C and atmospheric pressure. a. C. The gas is slowly heated, while the cylinder is allowed to freely expand. What kind of process is this? banc b. The smaller cylinder has a total mass of 1.5 kg. What temperature does the gas need to be for the cylinder to become fully extended? The cylinder can withstand an internal pressure of 20 atm. What's the maximum weight it can lift? e. d. A 100 kg weight is dropped on the cylinder while it is fully extended, causing it to rapidly compress. What kind of process is this? If the cylinder is fully depressed by this event, what is the peak pressure? The adiabatic constant for N2 is 7/5. f. If the weight is dropped from 2 m, assuming 1% of its energy is converted into thermal energy in the gas,…
