A calorimeter of heat capacity 100 J//K ...

A calorimeter of heat capacity `100 J//K` is at room temperature of `30^(@)C`. `100g` of water at `40^(@)C` of specific heat `4200 J//kg-K` is poured into the calorimeter. What is the temperature of water is calorimeter?

Text Solution

Verified by Experts

Let the temperature of water in calorimeter is t.
Then heat lost by water = heat gained by calorimeter
`(0.1) xx4200xx(40-t) = 100(t-30) implies 420xx40-420t-300 implies t=32.88^(@)C`
