Question 3
Equal moles of hydrogen and oxygen gases are placed in container with a pin-hole through which both can escape. What fraction of the oxygen escapes in the time required for one-half of the hydrogen to escape?
Question 4
If a gas expands at constant temperature, it indicates that
Question 5
vander Waal's real gas, act as an ideal gas, at which condition ?
Question 6
For an ideal gas, number of mol per litre in terms of its pressure P, temperature T and gas constant R is:
Question 7
Two closed bulbs of equal volume (V) containing an ideal gas initially at pressure p1 and temperature T1 are connected through a narrow tube of negligible volume as shown in the figure below. The temperature of one of the bulbs is then raised to T2. The final pressure pf is :
