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= (40.6 pm 0.2)^(@)C and theta_2= (78.3 pm 0.3 )^(@)C `
Rise is in temp. `theta= theta_2-theta_1 = 78.3 - 40.6 = 37.7^(@) C`
`Deltatheta = pm(Deltatheta_1+ Delta theta_2) = pm (0.2 + 0.3)= pm 0.5 ^(@) C" "therefore ` rise in temperature = `(37.7 pm 0.5)^(@)C `
