The number of extensive and intensive properties in the following list is respectively Mass, temperature, pressure, enthalpy, heat capacity, internal energy, density
Mass, enthalpy, heat capacity, internal energy.
Temperature, pressure, densityOne mole of an ideal gas at 300 K is expanded isothermally from an initial volume of 1 litre to 10 litres. The ΔE for this process is (R = 2cal mol−1 K−1)
For an isothermal process 
Hence 
A cyclic process 
is shown in 
diagram for an ideal gas. Which of the following diagram represents the same process?
Which of the following conditions are not suitable for a spontaneous reaction?
A heat engine carries one mole of an ideal mono-atomic gas around the cycle as shown in the figure. Select the correctoption:
A gas undergoes change from state 
to state 
. In this process, the heat absorbed and work done by the gas is 
and 
, respectively. Now gas is brought back to 
by another process during which 
of heat is evolved. In this reverse process of 
to 
:
(work done on the system).A diatomic ideal gas undergoes a thermodynamic change according to the P-V diagram shown in the figure. The total heat given to the gas is nearly
(use ln 2 = 0.7)
:
In 
diagram shown in figure 
is a semicircle. The work done in the process 
is
1) 
An ideal gas has temperature T1 at the initial state i shown in the P−V diagram. The gas has a higher temperature T2 at the final states a and b, which it can reach the paths shown. The change in entropy:
and 
An ideal monatomic gas is taken round the cycle 
as shown in the fig. The work done during the cycle is
Enthalpy change for freezing of 
of water at 
and 
is 
. Calculate the internal energy change in 
when 
of water is converted into ice?
water is converted into ice then internal energy is equal to enthalpy change for freezing at 1 bar and 
.
of water at 1 bar and 
temperature is 
.
.A system goes from 
to 
via two processes 
and 
shown in the figure. If 
and 
are the changes in internal energies in the processes I and Il respectively
to 
via two processes 
and 
shown in the figure. If
