A cylinder contains 10 kg of gas at a pressure of 107 N/m2 . The quantity taken out of the cylinder if the final pressure is . (temperature of gas is constant) is
A pendulum clock consists of an iron rod connected to a small, heavy bob. If it is designed to keep correct time at 20o C, how fast or slow will it go in 24 h at 40o C.
If the degree of freedom of a gas is f, then the ratio of two specific heats Cp /Cv is equal to :
