Question

Which statement is correct? (A) ((d H/d T))P<((d E/d T))V (B) (( dH / dT )) P +(( dE / dT )) V = R (C) (( dE / dV )) T for ideal gas is zero (D) All of these

Tardigrade Admin · Accepted Answer

For an ideal gas, dU or dE =0 when T is constant ∴ (( dU / dV )) T i.e., ( dU / dV ) at constant volume is 0 .

Q. Which statement is correct?

$(\frac{d H}{d T})_{P} < (\frac{d E}{d T})_{V}$

$(\frac{d H}{d T})_{P} + (\frac{d E}{d T})_{V} = R$

$(\frac{d E}{d V})_{T}$ for ideal gas is zero

All of these

For an ideal gas,
$d U$ or $d E = 0$ when $T$ is constant
$∴ (\frac{d U}{d V})_{T}$
i.e., $\frac{d U}{d V}$ at constant volume is 0 .

Q. Which statement is correct?

(dTdH​)P​<(dTdE​)V​

(dTdH​)P​+(dTdE​)V​=R

(dVdE​)T​ for ideal gas is zero

All of these

For an ideal gas, dU or dE=0 when T is constant ∴(dVdU​)T​ i.e., dVdU​ at constant volume is 0 .

$(\frac{d H}{d T})_{P} < (\frac{d E}{d T})_{V}$

$(\frac{d H}{d T})_{P} + (\frac{d E}{d T})_{V} = R$

$(\frac{d E}{d V})_{T}$ for ideal gas is zero

For an ideal gas,
$d U$ or $d E = 0$ when $T$ is constant
$∴ (\frac{d U}{d V})_{T}$
i.e., $\frac{d U}{d V}$ at constant volume is 0 .
