Question

Given that the work done in isothermal and reversible expansion is 6.4 kJ when 2 moles of an ideal gas expanded to double its volume. Calculate the temperature at which expansion takes place.

Answer 1

Given : 

Work = W_max = -6.4 kJ (For expansion)

= – 6400 J

Number of moles = 2

If  V₁ = x L

V₂ = 2 L

Temperature = T = ?

For isothermal reversible expansion,

∴ Temperature = T = 555.2 K
