The initial and final temperature of water as recorded by an observer are `(40.6 pm 0.2)^(@)C` and `(78.3 pm 0.3)^(@)C`. Calculate the rise in temperature.

Text Solution

Verified by Experts

Given `theta_(1)=(40.6pm0.2)^(@)Cand theta_(2)=(78.3 pm 0.3)^(@)C`
Rise in temperature `theta =theta_(2)-theta_(1)=78.3-40.6=37.7^(@)C,Deltatheta=pm(Delta theta_(1)+Deltatheta_(2))=pm(0.2+0.3)=pm0.5^(@)C`
`:.` Rise in temperature `= (37.7 pm 0.5)^(@)C`
