ANSWER ⤵️
The variation in the temperature is by fixed number of degree per min.
the temperature at the beginning of expt = 20°c.
Rate of temperature increase = 4°c per min
time for completion of expt = 15 min
Total rise in temperature = 15 × 4 = 60℃
temperature at the end of the experiment = 20+60 = 80℃
