Question

a body of mass 10gm was given a heat of 420J.find the rise in temperature​

Answer 1

Answer:

Given - energy supplied W=420J or Q=W/J=420/4.2=100 cal ,  

           m=10 g ,

now ,heat Q supplied to a body of mass m and of specific heat c to increase its temperature by Δθ , is given by ,

           Q=mcΔθ ,

we have , c=1cal/g  

o

C,m=10g ,

hence ,  100=10×1×Δθ ,

or          Δθ=100/10=10  

o

C
