Two closed bulbs of equal volume $$(V)$$ containing an ideal gas initially at pressure $${p_i}$$ and temperature $${T_1}$$ 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 $${T_2}.$$ The final pressure $${p_f}$$ is :

If Z is a compressibility factor, van der Waals equation at low pressure can be written as:

Z = 1 + $$RT \over Pb$$

Z = 1 - $$a \over VRT$$

Z = 1 - $$Pb \over RT$$

Z = 1 + $$Pb \over RT$$

For gaseous state, if most probable speed is denoted by C*, average speed by $$\mathop C\limits^{\_\_} $$ and mean square speed by C, then for a large number of molecules the ratios of these speeds are:

C*: $$\mathop C\limits^{\_\_} $$ : C = 1.128 : 1.225 : 1

C*: $$\mathop C\limits^{\_\_} $$ : C = 1.225 : 1.128 : 1

C*: $$\mathop C\limits^{\_\_} $$ : C = 1 : 1.225 : 1.128

C*: $$\mathop C\limits^{\_\_} $$ : C = 1 : 1.128 : 1.225
