A cyclinder with a movable piston contains `3 mol s` of hydrogen at standard temperature and pressure. The walls of the cyclinder are made of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of the gas increases, if the gas is compressed to half its original volume? Given `gamma= 1.4`.

A gas is compressed adiabatically to half its volume. By what factor does the pressure of the gas increase?

A heat insulating cylinder with a movable piston contins 5 moles of hydrogen at standard temperature and prssure if the gas is cmpressed to quarter of its original volume then the pressure of the gas is increased by (gamma=1.4)

A gas is copmressed isothermally to half its volume. BY what factor does the pressure of the gas increase ? Given gamma=1.4

Ten dm^(3) of hydrogen under 1 bar pressure are conained in a cylinder which has a movable piston. The piston is moved in until the same mass of gas occupies 2 dm^(3) at the same temperature. Find the pressure in the cylinder.

Two cyclinder A and B of equal capacity are connected to eachother via a stopcock. The cyclinder A contains an ideal gas at standard temperature and pressure, while the cyclindr B is completely evacuated. The entire system is thermally insulated. The stopcock is suddenly opened. Answer the following: (a) What is the final pressure of the gas in A and B? (b) What is the change in internal energy of the gas? (c ) What is the change in temperature of a gas? (d) Do the intermidiate states of the system (before settling to the final equilibrium state)lie on its P-V-T surface?

At constant pressure,a gas was compressed to half of its volume at 30^(@) C. To what temperature it should be heated so that its volume increases to double of its original volume ?

A weightless piston divides a thermally insulated cylinder into two parts of volumes V and 3V.2 moles of an ideal gas at pressure P = 2 atmosphere are confined to the part with volume V =1 litre. The remainder of the cylinder is evacuated. The piston is now released and the gas expands to fill the entire space of the cylinder. The piston is then pressed back to the initial position. Find the increase of internal energy in the process and final temperature of the gas. The ratio of the specific heats of the gas, gamma =1.5 .

A cylinder with a movable piston is filled at 25^(@)C with a gas that occupies a volume of 30.5 cm^(3) . If the maximum capacity of the cylinder is 45.8 cm^(3) , what is the highest temperature to which the cylinder can be heated at constant pressure without having the piston come out?
