Identify the correct statement when a fixed amount of ideal gas is heated in a container fitted with a movable piston always operating at constant pressure.

If an ideal gas is heated at constant pressure :

If an ideal gas is heated at constant pressure :

Heat supplied to an ideal gas sample at constant Pressure :

Heat supplied to an ideal gas sample at constant Pressure :

The temperature change occurring when one moles of a diatomic gas enclosed in a closed container fitted with a movable piston is heated by giving heat equal to 50 J and does net work 100 J is

A certain amount of an ideal gas is enclosed in a cylinder fitted with a movable piston. What would be the changes of the volume of the gas in the following processes? (i) The pressure of the gas is reduced by 25% at constant temperature. (ii) The temperature of the gas is increased by 50% constant pressure.

(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) ?
