The compressibility factor $(Z)$ for an ideal gas is ...... .

When an ideal gas undergoes unrestrained expansion,no cooling occurs because the molecules

The initial volume of a gas cylinder is $750.0 \ mL$. If the pressure of gas inside the cylinder changes from $840.0 \ mm \ Hg$ to $360.0 \ mm \ Hg$,what will be the final volume of the gas (in $L$)?

$A$ vessel of $120 \, mL$ capacity contains a certain amount of gas at $35^{\circ} C$ and $1.2 \, bar$ pressure. The gas is transferred to another vessel of volume $180 \, mL$ at $35^{\circ} C$. What would be its pressure?

Select one correct statement. In the gas equation,$PV = nRT$

In a closed vessel of volume $0.082 \, dm^3$ at $600 \, K$,the complete decomposition of methanol vapor occurs as follows: $CH_3OH_{(g)} \to CO_{(g)} + 2H_{2(g)}$. If $0.01 \, mol$ of methanol is taken initially,what will be the pressure generated in the vessel in $atm$?
