CSEC Physics · May/June 2010 · Paper 2 · Question 5(b)(i)

Another group determined the specific heat capacity of a liquid. It took 300 s for 0.1 kg of the liquid to be heated from 25°C to 50°C, with 13.6 KJ of energy supplied.

Assuming that no heat was lost and ignoring the heat capacity of the container, determine the value of the specific heat capacity of the liquid.

The mark scheme is shown once you've answered.
