What is the ratio of work done by a ideal monoatomic gas to heat supplied to it in isobaric process.

$$p-V$$ diagram of a diatomic gas is a straight line passing through origin. The molar heat capacity of the gas in the process will be:

The efficiency of a heat engine if the temperature of source $$227^0C$$ and that of sink is $$27^0C$$ nearly

The relation between U,P and V for an ideal gas is $$U=2+3PV$$. the gas is 

Consider a new system of units in which c (speed of light in vacuum), h(Planck's constant) and G (gravitational constant) are taken as fundamental units. Which of the following would correctly represent mass in this new system?

In an adiabatic expansion of as gas, its temperature: 

During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its temperature. The ratio of $$\frac { C _ { p } } { C _ { v } }$$ for the gas is

Which  is correct option for the expansion of an ideal gas under adiabatic cend?

When an ideal diatomic gas is heated at constant pressure, the fraction of heat energy supplied which is used in doing work to maintain pressure constant is
