A chamber contains monoatomic 'He' at STP, determine its number density

A rectangualr box (shown in figure) has a movable and smooth portition which can slide along the length of the box. Both chambers contains 1 mole of monoatomic gas ( gamma=(5)/(3) ) at a pressure walls of box and partition are thermally insulated. Due to heating, gas in left chamber expands until pressure in both chambers become 32P_(0) determine (a) The final temperature of gas in each chamber (b) The work done by the gas in the right chamber.

State the volume occupied by 40 gm of methane at STP, if its vapour density (V.D.) is 8

The density of oxygen is 1.43 g L^(-1) at STP. Determine the density of oxygen at 17^(@)C and 800 torr.

IF the density of nitrogen at STP is 1.25 g.L^-1 , determine the rms speed of nitrogen molecules.

A chamber contains a mixture of helium gas (He) and hydrogen gas (H_(2)) . The ration of the root-mean-square speed of the molecules of He and H_(2) is .............. .

Chamber containing vitreous humour is present

Calculate the volume occupied by 2.4 g of a gas at STP when its vapour density is 11.2
