2.-When water boils at 2 atm, the heat of vaporization is 2.2 106 J/kg, and the boiling point is 120ºC. At that pressure, 1 kg o
1 answer:
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.

The function and the first value stated for x are confusing.
Doing some research, I found that the problem is to evaluate the function
for x = - 1 and x 2.
The solution is:
1) For x = - 1
2) For x = 2
