Two containers of ideal gas with identical initial conditions experience identical temperature increases. Container A goes through the increase isobarically (with constant pressure) and container B isochorically (with constant volume). More heat was added to container A. More heat was added to container B. Equal amounts of heat were added to both containers. Any of the above relations is possible, depending on the work. 12.5 points Question 3 Say that a person is playing an amplified stringed instrument while riding...

Two large containers A and B of the same size are filled with different fluids. The fluids in containers A and B are maintained at 0° C and 100° C, respectively. A small metal bar, whose initial temperature is 100° C, is lowered into container A. After 1 minute the temperature of the bar is 90° C. After 2 minutes the bar is removed and instantly transferred to the other container. After 1 minute in container B, the temperature of...

A spherical bulb with a volume of 500 cm3 is evacuated to a negligibly small residual gas pressure and then close off. One hour later, the pressure in the vessel is found to be 2.00 × 10-7 atm because the bulb has a tiny hole in it. Assume that the surroundings are at atmospheric pressure, T = 300 K, and the average molar mass of molecules in the atmosphere is 28.8 g mol-1. a) Please calculate the radius of the...
