Describe, with the aid of a diagram an experiment to determine specific heat of vaporization of steam using the method of mixtures.
Describe, with the aid of a diagram an experiment to determine specific heat of vaporization of steam using the method of mixtures.
- The initial temperature θ0 and mass, m of water in the calorimeter are measured
- Steam from boiling water is passed into water in a calorimeter and after a reasonable temperature rise, flow of steam is stopped and final temperature, θf is recorded.
- Mass m2 of water in the calorimeter is then taken
- The mass of steam condensed, ms = (m2– m)
Given that the heat capacity of the calorimeter= C
Heat gained by steam = heat gained by water and calorimeter
mscv + msc(100- θf) = (m2 – m)c(θf – θ0) + C(θf – θ0)
cv = specific latent heat of vaporization
c= specific heat capacity of water
