Latent heat of vaporisation of water = 2260kJ/Kg
Specific heat capacity of water = 4185.5 J/Kg
Heat lost by steam = heat gained by the water and calorimeter
Formula :
Heat gained by water = mcФ
m = mass of water
c = specific heat capacity of water.
Ф = Change in temperature. = 40 - 32 = 8
Heat lost by steam = mLv + mcФ
Lv = latent heat of vaporisation
m = mass of steam.
Ф = 100 - 40 = 60
Doing the substitution :
2260000 × 0.005 + 60 × 0.005 × 4185.5 = m × 4185.5 × 8
12555.65 = 33484m
m = 12555.65/33484 = 0.37497 kg
= 0.37497 × 1000 = 374.97 kg
