Question 151 of 190

One mole of an ideal monatomic gas is compressed isothermally in a rigid vessel to double its pressure at room temperature, ${27}^{o}C$ . The magnitude of work done on the gas will be:

Show answer and solution

Answer: (B) $300R\ln 2$

Work done on gas

=nRT\ln \left(\dfrac{{P}_{f}}{{P}_{i}}\right)=R(300)\ln (2)=300R\ln 2

ThermodynamicsA Carnot engine working between temperatures $T_1 = 500\,\text{K}$ (source) and $T_2 = 300\,\text{K}$ (sink) absorbs $1000\,\text{J}$ of heat per cycle. The work done per cycle is:
ThermodynamicsFor an ideal gas undergoing a polytropic process $P V^n = \text{constant}$ , the molar heat capacity is given by $C = C_v + \frac{R}{1-n}$ . The process is isothermal when:
ThermodynamicsAn ideal gas undergoes an isothermal expansion from volume $V$ to $2V$ . The change in internal energy $\Delta U$ is:
ThermodynamicsConsider the following statements:
A. Zeroth law of thermodynamics gives concept of temperature
B. First law of thermodynamics gives concept of internal energy
C. In isothermal expansion of ideal gas, $\Delta Q \neq \Delta W$
D. Product of intensive and extensive variables is extensive
E. The ratio of any extensive variable to mass will be an extensive variable
Choose the correct combination of statements from the options given below:
ThermodynamicsThere are two vessels filled with an ideal gas where volume of one is double the volume of other. The large vessel contains the gas at 8 kPa at 1000 K while the smaller vessel contains the gas at 7 kPa at 500 K. If the vessels are connected to each other by a thin tube allowing the gas to flow and the temperature of both vessels is maintained at 600 K , at steady state the pressure in the vessels will be (in kPa).
ThermodynamicsAn ideal gas goes from an initial state to final state. During the process, the pressure of gas increases linearly with temperature.
A. The work done by gas during the process is zero.
B. The heat added to gas is different from change in its internal energy.
C. The volume of the gas is increased.
D. The internal energy of the gas is increased.
E. The process is isochoric (constant volume process)
