Question 466: Thermodynamics & KTG

Question

Two moles of helium gas are taken over the cycle $$ABCD,$$ as shown in the $$P$$-$$T$$ diagram.
Assuming the gas to be ideal the work done on the gas in taking it from $$A$$ to $$B$$ is :

Accepted Answer

$$A$$ to $$B$$ is an isobaric process. The work done
$$W = nR\left( {{T_2} - {T_1}} \right) = 2R\left( {500 - 300} \right) = 400R$$

Answer

$$300$$ $$R$$

Answer

$$400$$ $$R$$

Answer

$$500$$ $$R$$

Answer

$$200$$ $$R$$
