The gas equation $PV = nRT$ is applicable for which of the following conditions?

The following $P$ vs $V$ curve is plotted. What is the relation between $T_1$,$T_2$ and $T_3$?

At $25 \, ^\circ C$ temperature and $760 \, mm \, Hg$ pressure,the volume of a gas is $600 \, mL$. Calculate the pressure when the volume of this gas becomes $640 \, mL$ at $10 \, ^\circ C$ temperature. Use the ideal gas equation: $\frac{p_1 V_1}{T_1} = \frac{p_2 V_2}{T_2}$

If $P, V,$ and $T$ represent the pressure,volume,and temperature of a gas,respectively,which of the following represents Boyle's Law correctly?

If $P$,$V$,and $T$ represent the pressure,volume,and temperature of a gas respectively,which is the correct representation of Boyle's Law?

The density of gas $A$ is twice that of gas $B$ at the same temperature. The molecular weight of gas $B$ is twice that of gas $A$. The ratio of the pressure of gas $A$ to gas $B$ will be:
