1.	A sample of a gas contains N1 molecules and the total kinetic energy at −123∘C is E1 ergs. Another sample of a gas at 27∘C has a total kinetic energy as 2E1 ergs. Assuming gases to be ideal, the number of gas molecules in the second sample will be:
Answer» A sample of a gas contains $N_{1}$ molecules and the total kinetic energy at $- 123^{\circ}$ C is $E_{1}$ ergs. Another sample of a gas at $27^{\circ}$ C has a total kinetic energy as $2 E_{1}$ ergs. Assuming gases to be ideal, the number of gas molecules in the second sample will be:
