During the isothermal expansion,a confined ideal gas does $(-150) \ J$ of work against its surroundings. This means that

Two identical containers $A$ and $B$ with frictionless pistons contain the same ideal gas at the same temperature and the same volume $V$. The mass of the gas in $A$ is ${m_A}$ and that in $B$ is ${m_B}$. The gas in each cylinder is now allowed to expand isothermally to the same final volume $2V$. The changes in the pressure in $A$ and $B$ are found to be $\Delta P$ and $1.5 \Delta P$ respectively. Then:

If an ideal gas is compressed isothermally, which of the following statements is true?

$A$ perfect gas of volume $5 \ L$ is compressed isothermally to a volume of $1 \ L$. The $r.m.s.$ speed of the molecules will

When heat is given to a gas in an isothermal change,the result will be

What is the value of the specific heat of a gas during an isothermal process?
