Arrange the states of matter (solid,liquid,and gas) in increasing order of their thermal energy.

Which state of matter has a definite volume but no definite shape?

$A$ mixture of one mole each of $H_2$,$He$ and $O_2$ are enclosed in a cylinder of volume $V$ at temperature $T$. If the partial pressure of $H_2$ is $2 \ atm$,the total pressure of the gases in the cylinder is $....... \ atm$

Provide the mathematical expression for Dalton's law of partial pressure.

$300 \ mL$ of a gas '$x$' of molar mass $32 \ g \ mol^{-1}$ is effused in $25 \ s$. What volume of methane would effuse in the same time (in $mL$)?

Which of the following statements is incorrect?
