Answer:

B

Explanation:

Heat energy of a substace can be calculated using

Q = mcθ

where Q = Heat energy

           m =mass

           c = specific heat capacity

           θ =temperature difference

Temperature difference is final temperature - initial temperature.

So we get,

Q = 1 × 600×(100-20)

   = 48000 J
