A fixed mass of a gas is first heated isobarically to double the volume and then cooled isochorically

A fixed mass of a gas is adiabatically made to expand to double its volume and then isochorically heated to bring the gas to the original pressure. The ratio of final to initial temperature will be

At constant pressure, a fixed mass of a gas is heated form 0^@C to 30^@C . Find the ratio of the volumes of the gas at 0^@C and 30^@C .

A given mass of a perrfect gas is first heated in a small and then in a large vessel, such that their volumes remain unaltered. The P-T curves are-

A mole of an ideal gas initially at a temperature T_(1)=290K expands isobarically until its volume increases 2 times. Next the gas is cooled isochorically to its initial temperature T_(1) .Find (a) the incement DeltaU in the internal energy of the gas, (b) the work A done by the gas (c) the amount of the heat Q received by the gas.

If the pressure of a given mass of gas is reduced to half and temperature is doubled simultaneously the volume will be

If the pressure of a given mass of gas is reduced to half and temperature is doubled simultaneously the volume will be

For a given mass of gas isobar is the graph drawn between

(i) An adiabatic cylinder contains an ideal gas. It is fitted with a freely movable insulating piston. In one experiment the piston is pulled out very fast to double the volume of the gas. In another experiment starting from same initial state, the piston is pulled out very slowly to double the volume of the gas. At the end of which experiment the final pressure of the gas will be higher? (ii) An ideal gas is contained in a cylinder fitted with a movable piston. In an experiment ‘A’ the gas is allowed to perform a work W (gt 0) on the surrounding during an isobaric process and thereafter the pressure of the gas is reduced isochorically to half the initial value. At the end of the experiment the temperature of the gas is T_(A) . In a different experiment ‘B’ the pressure of the gas is reduced to half in an isochoric process and then the gas performs a work W on the surrounding during an isobaric process. At the end of the experiment the gas temperature is T_(B) . Which is higher, T_(A) or T_(B) ?
