One mole of an ideal monatomic gas undergoes a process described by the equation $P{V}^3=\text{constant}$. The heat capacity of the gas during this process is:

The temperature inside a refrigerator is $t_2^{\circ }\text{C}$ and the room temperature is $t_1^{\circ }\text{C}$. The amount of heat delivered to the room for each joule of electrical energy consumed ideally will be:

A given sample of an ideal gas occupies a volume $V$ at a pressure $P$ and absolute temperature $T$. The mass of each molecule of the gas is $m$. Which of the following gives the density of the gas?

A body of mass $m$ is attached to the lower end of a spring whose upper end is fixed. When the mass $m$ is slightly pulled down and released, it oscillates with a time period of $3\text{s}$. When the mass $m$ is increased by $1\text{kg}$, the time period of oscillations becomes $5\text{s}$. The value of $m$ in $\text{kg}$ is:

The second overtone of an open organ pipe has the same frequency as the first overtone of a closed pipe $L$ meter long. The length of the open pipe will be:
