Heat is supplied uniformly at the rate of 100W to 1.0 x 10^-2kg of a liquid for 20 seconds. If the temperature of the liquid rises by 5^oC, then the specific heat capacity of the liquid is

2.0 x 10²Jkg^-1k^-1

2.0 x 10²Jkg^-1

4.0 x 10⁴Jkg^-1k^-1

4.0 x 10⁴kg^-1

8.4 x 10³Jkg^-1k^-1

Correct answer is C

Heat energy = Electrical energy

mc\(\theta\) = power x time

5 x 1 x 10^-2 x C = 100 x 20

C = 4.0 x 10⁴Jkg^-1k^-1
