Question

In an experiment to determine the specific latent heat of vaporisation of steam L, the following measurements were taken :

Mass of calorimeter + stirrer = x kg

Mass of water = y kg

Mass of condensed steam = A kg

Initial temperature of water = t1ºC

Final temperature of mixture = t2ºC

Given : Specific heat capacity of calorimeter and water are S1 and S2 respectively. Express L in terms of above data.


please help ASAP ​

Answer:

Let final temperature of mixture is t.

Let the specific heat of solid is c
