When an ideal gas is compressed isothermally,its pressure:

One mole of an ideal gas expands at a constant temperature of $300 \, K$ from an initial volume of $10 \, L$ to a final volume of $20 \, L$. The work done in expanding the gas is ...... $J$. $(R = 8.31 \, J/mol \cdot K)$

$Assertion :$ The isothermal curves intersect each other at a certain point.
$Reason :$ The isothermal change takes place slowly,so,the isothermal curves have very little slope.

Heat is given to an ideal gas in an isothermal process. Then

An ideal gas at pressure $P$ is enclosed in a container that is placed in a reservoir at temperature $T$. If the volume of the gas is increased to two times its original value, then the new pressure $P^{\prime}$ is equal to:

The volume of an ideal gas is $1 \, L$ and its pressure is equal to $72 \, cm$ of mercury column. The volume of the gas is made $900 \, cm^3$ by compressing it isothermally. The increase in the pressure of the gas will be ...... $cm$ of mercury.
