Question

Certain amount of heat supplied to an ideal gas under isothermal condition will result in (A) an increase in the internal energy of the gas (B) external work done and a change in temperature (C) a rise in temperature (D) external work done by the system

For isothermal process, Δ T= constant As we know that, from first law of thermodynamics, Δ Q=Δ U+Δ W=n CV Δ T+Δ W ⇒ Δ Q=Δ W[∵ Δ T=0] Hence, heat supplied to an ideal gas under isothermal condition will result in external work done by the system.

Q. Certain amount of heat supplied to an ideal gas under isothermal condition will result in

an increase in the internal energy of the gas

external work done and a change in temperature

a rise in temperature

external work done by the system

For isothermal process, $Δ T =$ constant
As we know that, from first law of thermodynamics,
$Δ Q = Δ U + Δ W = n C_{V} Δ T + Δ W$
$\Rightarrow Δ Q = Δ W [∵ Δ T = 0]$
Hence, heat supplied to an ideal gas under isothermal condition will result in external work done by the system.

For isothermal process, ΔT= constant As we know that, from first law of thermodynamics, ΔQ=ΔU+ΔW=nCV​ΔT+ΔW ⇒ΔQ=ΔW[∵ΔT=0] Hence, heat supplied to an ideal gas under isothermal condition will result in external work done by the system.
