The P-V diagram for an ideal gas in a piston cylinder assembly undergoing a thermodynamic process is shown in the figure. The process is (1) isothermal (2) adiabatic (3) isochoric (4) isobaric
The efficiency of a Carnot engine depends upon (1) the temperature of the source only (2) the temperature of the sink only (3) the temperatures of the source and sink (4) the volume of the cylinder of the engine
A heat engine is involved with exchange of heat of 1915 J, –40J, +125 J and –QJ, during one cycle achieving and efficiency of 50.0%. The value of Q is : (1) 400 J (2) 980 J (3) 640 J (4) 40 J
An engine takes in 5 moles of air at 20°C and 1 atm, and compresses it adiabatically to 1/10th of the original volume. Assuming air to be a diatomic ideal gas made up of rigid molecules, the change in its internal energy during this process comes out to be ...
In which of the following processes, heat is neither absorbed nor released by a system? (1) Isothermal (2) Adiabatic (3) Isobaric (4) Isochoric
Increase in temperature of a gas filled in a container would lead to : (1) increase in its mass (2) increase in its kinetic energy (3) decrease in its pressure (4) decrease in intermolecular distance
A gas can be taken from A to B via two different processes ACB and ADB. When path ACB is used 60 J of heat flows into the system and 30 J of work is done by the system. If path ADB is used work done by the system is 10 J. The heat Flow into the system in ...
