Two containers $$A$$ and $$B$$ are partly filled with water and closed. The volume of $$A$$ is twice that of $$B$$ and it contains half the amount of water in $$B.$$ If both are at the same temperature, the water vapour in the containers will have pressure in the ratio of
A.
$$1:2$$
B.
$$1:1$$
C.
$$2:1$$
D.
$$4:1$$
Answer :
$$1:1$$
Solution :
Vapour pressure of a substance is independent of amount of substance. It depends only on temperature. So they have ratio of $$1:1.$$

The average translational kinetic energy of $${O_2}$$ (relative molar mass 32) molecules at a particular temperature is $$0.048\,eV.$$ The translational kinetic energy of $${N_2}$$ (relative molar mass 28) molecules in $$eV$$ at the same temperature is
A vessel contains 1 mole of $${O_2}$$ gas (relative molar mass 32) at a temperature $$T.$$ The pressure of the gas is $$P.$$ An identical vessel containing one mole of $$He$$ gas (relative molar mass 4) at a temperature $$2\,T$$ has a pressure of
