In the reaction given below, at constant pressure, the work done by system on surrounding is?

In an adiabatic process on a gas with $$\gamma=1.4$$, the pressure is increased by 0.5%. The volume decreases by about

Two different ideal diatomic gases A and B are initially in the same state. A and B are then expanded to the same final volume through adiabatic and isothermal processes respectively. If $$P_A, P_B$$ and $$T_A, T_B$$ represents the final pressure and temperature of A and B respectively then

In the following P-V diagram of an ideal gas, AB and CD are isothermal whereas BC and DA are adiabatic process. The value of $$V_B/V_C$$ is

Two ideal gases A & B are going through adiabatic process. Choose the correct option.

An ideal gas has an initial pressure of 3 pressure units and an initial volume of 4 volume units. The table gives the final pressure and volume of the gas (in those same units) in four processes. Which processes start and end on the same isotherm

The adiabatic bulk modulus of hydrogen gas $$(\gamma=1.4)$$ at NTP is

Find the amount of heat released if $$1\;kg$$ steam at $$200^{\circ}C$$ is converted into $$-20^{\circ}C$$ ice.

If molar heat capacity of the given process (as shown in figure) is C, then

The molar heat capacity at constant pressure for Nitrogen gas at STP is nearly 3.5 R. Now, when the temperature is increased, it gradually increases and approaches 4.5 R. The most appropriate reason for this behaviour is that at high temperatures
