The initial and final temperatures of a ...

The initial and final temperatures of a liquid in a container are observed to be `75.4 pm 0.5^(@)C` and `56.8 pm 0.2^(@)C`. Find the fall in the temperature of the liquid.

Text Solution

Verified by Experts

`t_(1) = (56.4 pm 0.5)^(@)C , t_(2) = (56.8 pm 0.2)^(@)C`
Fall in temperature = `(75.4 pm 0.5^(@)C) - (56.8 pm 0.2^(@)C)`
`t = (18.6)^(@)C`
