Question

3kg of water is to be heated from 30 degree Celsius to 80 degree Celsius.using a heating coil which draws a current of 6A from a 200V mains.if the specific heat capacity of water is 1200kg^minus 1k^minus 1 the heating time required is

Answer 1

Explanation:

A heating coil is immersed in a calorimeter of heat capacity 50JC

−1

containing 1.0 kg of a liquid of specific heat capacity 450JKg

−1
