The student places 0.5 kg of potato into a pan of water.
during cooking, the temperature of the potato increases from 20 °c to 100 °c
the specific heat capacity of the potato is 3400 j/kg °c
calculate the change in thermal energy of the potato.
use the equation:
change in thermal energy = mass * specific heat capacity temperature change
