pooja needs 15 kg of water at 38 degree Celsius to take a bath, but her water is only at 20 degree Celsius. calculate the minimum amount of heat energy she requires to heat the water to the required temperature.
Answers: 2
![Q=m*c_{p}*(T_{f} - T_{i}) \\where:\\C_{p}=specific water heat = 4.18 [\frac{kJ}{kg*K}] \\m = mass = 15 [kg]\\T_{f}= Final temperature = 38 [C]\\T_{i}=20[C]](/tpl/images/0793/1756/3864d.png)
