A closed vessel contains equal number of oxygen and hydrogen molecules. Consider the following statements:
1. The average speed of hydrogen molecules is greater.
2. The two gases have different average energies.
3. Hydrogen molecules strike the walls more often.
4. Weight of hydrogen is th of the weight of oxygen.
Wrong statements are –
(A) 1 and 2
(B) 2 and 3
(C) 1 and 3
(D) 2 and 4
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 plot of pressure versus for a gas at constant temperature is given below:
