In a reaction 4 kJ of heat is released. If the same amount of heat is supplied to 200 g of water at `25^(@)`, what will be the final temperature of water ? [Given : molar heat capacity of water `=75.24 J. K^(-1) " mol"^(-1)`]

Text Solution

Verified by Experts

`q= m C_(P)(T_(2)-T_(1))`
or, `-4xx10^(3)=200xxC_(P)(T_(2)-298)`
`= 200xx(75.24)/(18)(T_(2)-298)`
`therefore T_(2)=303 K`
