At the same temperature., nitrogen gas is ……………….solube in water than oxygen.

At a same temperature, hydrogen is more soluble in water than helium. Which of them will have a higher value of k_H and why?

At the same external pressure , more the temperature lesser is the solubility of a gas in water.

Two beakers of capcatity 500 mL were taken one of these beakers labelled as "A" was filled with 400 mL water whereas the beaker labelled "B" was filled with 400 mL of 2 M solution of NaCl. At the same temperature both the beakers were placed in close containers of same material and same capacity as shown in the figure given below: At a given temperature, whihc of the following statement is correct about the vapour pressure of pure water and that of NaCl solution.

The volume of vessel A is thrice the volume of another vessel of another vessel B and both of them are filled with the same gas. If the gas in vessel A is at thrice the temperature and thrice the pressure as compared to that of gas in vessel B. what is ratio of gas molecules in the two vessels?

A vessel is filled with a gas at a pressure of 76 cm of mercury at a certain temperature. The mass of the gas is increased by 50% by introducing more gas in the vessel at the same temperature. Find out the resultant pressure of the gas.

At what temperature, the molecules of nitrogen will yhave the same rms velocity as the molecules of oxygen at 127^@ C ?

Water in U-tube executes S.H.M. Will the time period for mercury filled up to the same height in the U-tube be lesser or greater than that in case of water?

Fill in the blanks: The ratio of r.m.s. speed of an hydrogen and an oxygen molecule at the same temperature is ………….

Two ballons are filled, one with pure He gas and the other by air respectively. If the pressure and temperature of these ballon are same, then the number of molecule sper unit volume is:
