An ideal gas expands against a constant external pressure of $3 \ atm$ from $4 \ dm^3$ to $6 \ dm^3$. The work done during this process is ..... $J$.

What do the gas laws,such as Boyle's law,Charles's law,etc.,state?

Hydrogen gas is present in compartment $A$ and compartment $B$ as shown in the following figure. If the valve is opened,then the final pressure in the compartments is ............. $atm$. [Assume the temperature of each vessel remains constant at its initial value]

The vapors of $1 \ g$ of an element occupy $2.5625 \ L$ exerting a pressure of $0.5 \ atm$ at $1000 \ K$. What is the molar mass (in $g \ mol^{-1}$) of the element? (Assume vapors follow ideal gas equation. Given $R=0.082 \ L \ atm \ mol^{-1} \ K^{-1}$)

$2 \ g$ of $O_2$ at $27 \ ^\circ C$ and $760 \ mm$ of $Hg$ pressure has volume ............. $L$.

Which of the following graphs represents Boyle's law?
