Question

Solve the first numerical ans are given below plzz confirm nd then give ans in detail....

Answer 1

The Heat energy of the system is given by

$q = mcdt$

here from the graph

q=3600

dt=100

and C in the question=0.8

then putting values we get

3600=m80

m=45g

also in the graph the interval is BC is when it changes it's state

so here Q=mL or L=Q/m

L=3600/45=80
