Question #68275
What is the total amount of heat calories required to increase the temperature of 28 grams of water from 22 ^C to 42^C?
Expert's answer
Solution:
The amount of heat and the change in temperature are related as:
where is the specific heat capacity and is the mass of the water. The former is 1 cal/(°C·kg),
and the latter is 28·10 -3 kg. Thus, we can calculate the amount of heat:
Answer: 0.56 cal
