The kinetic energy for 14 grams of nitrogen gas at 127°C is nearly -
(mol. mass of nitrogen = 28 and gas constant = 8.31JK–1mol–1)
1. 1.0 J
2. 4.15 J
3. 2493 J
4. 3.3 J
Pressure versus volume graph for a real gas and an ideal gas is shown below:
The correct statement among the following is -
1. Real gases show a large deviation from ideal behaviour at low pressure.
2. Real gases show a very small deviation from ideal behaviour at low pressure.
3. Real gases do not behave ideally under any conditions at low pressure.
4. None of the above statements is correct
A helium atom is two times heavier than a hydrogen molecule. At 298 K, the average kinetic energy of a helium atom is-
1. Same as that of a hydrogen molecule
2. Half that of a hydrogen molecule
3. Two times that of a hydrogen molecule
4. Four times that of a hydrogen molecule
