Types Of Processes

In thermodynamic processes which of the following statements is not true?

1.	In an adiabatic process, the system is insulated from the surroundings.
2.	In an isochoric process, pressure remains constant.
3.	In an isothermal process, the temperature remains constant.
4.	In an adiabatic process

One mole of an ideal gas goes from an initial state to the final state with two processes. It first undergoes isothermal expansion from volume to and then its volume is reduced from to at constant pressure. The correct diagram representing the two processes is:

1.		2.
3.		4.

During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its temperature. The ratio of for the gas is:
1.
2.
3.
4.

Thermodynamic processes are indicated in the following diagram: 

Match the following:

Column-I		Column-II
	Process I		Adiabatic
	Process II		Isobaric
	Process III		Isochoric
	Process IV		Isothermal

1.
2.
3.
4.

In which of the following processes, the heat is neither absorbed nor released by a system?

1.	isochoric	2.	isothermal
3.	adiabatic	4.	isobaric

The diagram for an ideal gas in a piston-cylinder assembly undergoing a thermodynamic process is shown in the figure. The process is:

1.	adiabatic	2.	isochoric
3.	isobaric	4.	isothermal
