A container is filled with an ideal diatomic gas to a pressure and volume of P1 and V1, respectively. The gas is then warmed in a two-step process that increases the pressure by a factor of four and the volume by a factor of three. Determine the amount of energy transferred to the gas by heat if the first step is carried out at constant volume and the second step at constant pressure. (Use any variable or symbol stated above as necessary.) Q =

Consider a sample containing 1.85 mol of an ideal diatomic gas. (a) Assuming the molecules rotate but do not vibrate, find the total heat capacity of the sample at constant volume. nCv = J/K (b) Assuming the molecules rotate but do not vibrate, find the total heat capacity of the sample at constant pressure. nCp = J/K (c) Assuming the molecules both rotate and vibrate, find the total heat capacity of the sample at constant volume. nCv = J/K Assuming the molecules both rotate and vibrate, find the total heat capacity of the sample at constant pressure. nCp = J/K

Two disks are initially at rest, each of mass M = 4 kg, connected by a string between their centers, as shown in the figure. The disks slide on low-friction ice as the center of the string is pulled by a string with a constant force F = 15 N through a distance d = 2.7 m. The disks collide and stick together, having moved a distance b = 2.0 m horizontally. (a) What is the final speed of the stuck-together disks? vf = m/s (b) When the disks collide and stick together, their temperature rises. Calculate the increase in internal energy of the disks, assuming that the process is so fast that there is insufficient time for there to be much transfer of energy to the ice due to a temperature difference. (Also ignore the small amount of energy radiated away as sound produced in the collisions between the disks.) ΔEinternal = J
