Two samples $$A$$ and $$B$$ of a gas initially at the same pressure and temperature are compressed from volume $$V$$ to $$\displaystyle\frac{V}{2}$$ ($$A$$ isothermally and $$B$$ adiabatically). The final pressure of $$A$$ is

Four curves $$A$$, $$B$$, $$C$$ and $$D$$ are drawn in figure for a given amount of gas. The curves which represent adiabatic and isothermal changes are.

Compute the change in internal energy (in joules)

Compute the work done (in joules)

A container of volume $$1\:m^3$$ is divided into two equal compartments by a partition. One of these compartments contains an ideal gas at $$300\:K$$. The other compartment is vacuum. The whole system is thermally isolated from its surroundings. The partition is removed and the gas expands to occupy the whole volume of the container. Its temperature now would be :

An ideal gas $$\displaystyle\left(\frac{C_p}{C_v}=\gamma\right)$$ is taken through a process in which the pressure and the volume vary as $$P=aV^b$$. The value of b for specific heat capacity as zero is

A thermally insulated container is divided into two parts by a screen. In one part the pressure and temperature are $$P$$ and $$T$$ for an ideal gas filled. In the second part it is vacuum. If now a small hole is created in the screen, then the temperature of the gas will

In an adiabatic process pressure is increased by $$\displaystyle\frac{2}{3}\%$$ if $$\displaystyle\frac{C_p}{C_v}=\frac{3}{2}$$. Then the volume decrease by about

For process 1, $$\Delta U$$ is positive, for process 2, $$\Delta U$$ is zero and for process 3, $$\Delta U$$ is negative. Find the parameters indicating $$x$$ and $$y$$ axes.

On an isothermal process, there are two points $$A$$ and $$B$$ at which pressures and volumes are $$(2P_o,\:V_o)$$ and $$(P_o,\:2V_o)$$ respectively. If $$A$$ and $$B$$ are connected by a straight line, find the pressure at a POINT on this straight line at which temperature is maximum
