Calculate the work done when an ideal gas expands isothermally and reversibly in a piston and cylinder assembly for expansion of a gas at 300 K from initial pressure 10 bar to final pressure 1 bar.

Answer:

[tex]W=5743.1077\ J[/tex]

Explanation:

The expression for the work done is:

[tex]W=RT \ln \left( \dfrac{P_1}{P_2} \right)[/tex]

Where,

W is the amount of work done by the gas

R is Gas constant having value = 8.314 J / K mol

T is the temperature

P₁ is the initial pressure

P₂ is the final pressure

Given that:

T = 300 K

P₁ = 10 bar

P₂ = 1 bar

Applying in the equation as:

[tex]W=8.314\times 300 \ln \left( \dfrac{10}{1} \right)[/tex]

[tex]W=300\times \:8.314\ln \left(10\right)[/tex]

[tex]W=2.30258\times \:2494.2[/tex]

[tex]W=5743.1077\ J[/tex]
