A gas such as carbon monoxide would be most likely to obey the ideal gas law at-

1. High temperature and low pressure

2. Low temperature and high pressure

3. High temperature and high pressure

4. Low temperature and low pressure

The kinetic energy for 14 grams of nitrogen gas at 127°C is nearly -

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

2. Half that of a hydrogen molecule

3. Two times that of a hydrogen molecule 

4. Four times that of a hydrogen molecule
