A balloon containing an ideal gas is initially kept in an evacuated and insulated room. The balloon ruptures and the gas fills up the entire room. Which one of the following statements is TRUE at the end of above process ?

The main cause of the irreversibility is

Select the correct answer using the code given below:

Which of these are intensive properties?

In highly rarefied gases, the concept of this loses validity

Isothermal compression of air in a Stirling engine is an example of

Ice kept in a well insulated thermo flask is an example of which system?

A frictionless piston-cylinder device contains a gas initially at 0.8 MPa and 0.015 m³. It expands quasi-statically at constant temperature to a final volume of 0.030 m3. The work output (in kJ/kg) during this process will be:

A gas expands in a frictionless piston-cylinder arrangement. The expansion process is very slow, and is resisted by an ambient pressure of 100 kPa. During the expansion process, the pressure of the system (gas) remains constant at 300 kPa. The change in volume of the gas is 0.01 m³. The maximum amount of work that could be utilized from the above process is:

Find the maximum work obtainable if a reversible heat engine is installed between the two incompressible substances of equal masses 5 kg and specific heat capacity of 4.2 kJ/kg.K which are at 400 K and 900 K.

In a new temperature scale say °ρ, the boiling and freezing points of water at one atmosphere are 100°ρ and 300°ρ respectively. Correlate this scale with the Centigrade scale. The reading of 0°ρ on the Centigrade scale is:

Which one of the following is the correct sequence of the three processes A, B and C in the increasing order of the amount of work done by a gas following idealgas expansions by these processes?
