Jason runs a bath that contains 200 kg of water. a. How much energy is needed to heat the cold water to 38 degrees celsius in the summer. b. How much extra energy is needed to heat a bath of 200 kg of water in the winter.
+33615 The energy required is given by mass*specific heat capacity*temperature rise
The specific heat capacity of water (in this temperature range) is 4184 J/(kg.degC)
To answer your question you need to specify the starting temperature of the water as well, as it is the temperature difference that matters.
