Question

If Δ U represents the increase in internal energy and W the work done by the thermodynamic system, then (A) Δ U = - W is an isothermal process (B) Δ U = W is an isothermal process (C) Δ U = - W is an adiabatic process (D) Δ U = W is an adiabatic process

Tardigrade Admin · Accepted Answer

Correct answer is (c) Δ U = - W is an adiabatic process

Q. If $Δ U$ represents the increase in internal energy and W the work done by the thermodynamic system, then

$Δ U = - W$ is an isothermal process

$Δ U = W$ is an isothermal process

$Δ U = - W$ is an adiabatic process

$Δ U = W$ is an adiabatic process

$Δ U = W$ is an isochoric process

Correct answer is (c) $Δ U = - W$ is an adiabatic process

Q. If ΔU represents the increase in internal energy and W the work done by the thermodynamic system, then

ΔU=−W is an isothermal process

ΔU=W is an isothermal process

ΔU=−W is an adiabatic process

ΔU=W is an adiabatic process

ΔU=W is an isochoric process

Correct answer is (c) ΔU=−W is an adiabatic process
