We need to set up and solve all of the angle measures add up to 180°
a) Find the work done when 1 kg of steam is formed at that temperature.
- p = pressure = 2 atm =2 101325.2738 = 202651 Pa
- V₁ = volume of 1kg of water = 10⁻³ m³
- V₂ = volume of 1 kg of steam = 0.824 m³
- Lf = heat of vaporization of water = 2.2 10⁶ J/kg
- m = mass of water = 1 kg
b) Calculate the increase in internal energy.
