Select the correct statement.

• A

  The product of pressure and volume of an ideal gas will be equal to translational kinetic energy of the molecules.
• Correct answer
  B

  The temperature of gas is $-73^{\circ} \mathrm{C}$. When the gas is heated to $527^{\circ} \mathrm{C}$, the r.m.s. speed of the molecules is doubled.
• C

  The temperature of gas is $-100^{\circ} \mathrm{C}$. When the gas is heated to $+627^{\circ} \mathrm{C}$, the r.m.s. speed of the molecules is four times.
• D

  The product of pressure and volume of an ideal gas will be equal to half the translational kinetic energy.

Hence, the correct answer is option: 'B'.
