Question

An immersion heater rated 1 5 Kw is used to heat 10 kg of water
calculate the time taken in raising the tempeatureof water by 32
degree Celsius Specific heat capacity of water is 4200 J/kg degree
celsius

Vara · Accepted Answer

Heat energy required to raise the temperature of water:E=mc△t   =10×4200×32   =1
344×106 JTime taken:t=EP =1 344×1061
5×103 =896 s =89660  min =14
9 minutes
