Question

The graph shown in the figure represent change in
the temperature of 5 kg of a substance as it abosrbs
heat at a constant rate of 42 kJ min-1. The latent
heat of vapourazation of the substance is
Temperature (°C)​

Answer 1

Answer:

where is the graph ????

Answer 2

Heya friend!!

Explanation:Well if its the graph which I have then the answer  goes like this

There is a constant temperature line at T=125  that is its vaporization temperature , and heat supplied during that duration is latent heat of vaporization.  

Heat absorbed is 42×(35−25)=5×L

so, L=84 kJ/kg

Hope that helps!
