Answer:

The value of ∆T ( change in Temperature), would be 20 degree C.

Explanation:

∆T means the change in Temperature. The final temperature minus the starting temperature gives the change in temperature.

50-30 = 20 degree C.

In this case, we have a positive 20 degree C which means we gained energy. If it was a negative value, you would lose energy.
