A certain gas is isothermally compressed to (1/3)ʳᵈ of its initial volume (V₀=3 litre) by applying required pressure. If the bulk modulus of the gas is 3×10⁵ N/m², the magnitude of work done on the gas is J.

Answer: 989

Solution

For an isothermal process the bulk modulus equals the pressure, so P₀=3×10⁵
