A gas undergoes an isothermal process. The specific heat capacity of the gas in the process is:
1. infinity
2. \(0.5\)
3. zero
4. \(1\)

Two cylinders A and B of equal capacity are connected to each other via a stop cock. A contains an ideal gas at standard temperature and pressure. B is completely evacuated. The entire system is thermally insulated. The stop cock is suddenly opened. The process is : 

1. adiabatic 

2. isochoric 

3. isobaric 

4. isothermal 

The \((\text{P-V})\) diagram for an ideal gas in a piston-cylinder assembly undergoing a thermodynamic process is shown in the figure. The process is:

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

In which of the following processes, the heat is neither absorbed nor released by a system?
1. isochoric
2. isothermal
3. adiabatic
4. isobaric

\(1\) g of water of volume \(1\) cm³ at \(100^\circ \text{C}\) is converted into steam at the same temperature under normal atmospheric pressure \(\approx 1\times10^{5} \) Pa. The volume of  steam formed equals \(1671\) cm³. If the specific latent heat of vaporization of water is \(2256\) J/g, the change in internal energy is:
1. \(2423\) J
2. \(2089\) J
3. \(167\) J
4. \(2256\) J

A sample of 0.1 g of water at \(100^{\circ}\mathrm{C}\)$$ and normal pressure (1.013 × 10⁵ Nm^–2) requires 54 cal of heat energy to convert it into steam at \(100^{\circ}\mathrm{C}\)$$. If the volume of the steam produced is 167.1 cc, then the change in internal energy of the sample will be:
1. 104.3 J
2. 208.7 J
3. 42.2 J
4. 84.5 J

The volume (V) of a monatomic gas varies with its temperature (T), as shown in the graph. The ratio of work done by the gas to the heat absorbed by it when it undergoes a change from state A to state B will be:
