Question 822: Thermodynamics & KTG

Question

In a thermodynamic system, $$\Delta U$$ represents the increases in its internal energy and dW is the work done by the system then correct statement out of the following is

Accepted Answer

For an isothermal process, $$\Delta \mathrm{U}=0$$. According to first law of thermodynamics,
$$\Delta \mathrm{Q}=\Delta \mathrm{U}+\mathrm{dW}$$
For an adiabatic process,
$$\begin{aligned}
\Delta Q & =0 \
	herefore \quad \Delta U & =-d W
\end{aligned}$$
$$	herefore \quad$$ It is an adiabatic process.

Answer

$$\Delta \mathrm{U}=\mathrm{dW}$$ is an isothermal process

Answer

$$\Delta \mathrm{U}=-\mathrm{dW}$$ is an adiabatic process

Answer

$$\Delta \mathrm{U}=-\mathrm{dW}$$ is an isothermal process

Answer

$$\Delta \mathrm{U}=\mathrm{dW}$$ is an adiabatic process
