Calculate the amount of energy required to raise the temperature of the water from 15 0C to 100 0C. WebHeat and temperature are a closely related topic, and as such, the difference between the two can be a bit confusing. The core difference is that heat deals with thermal energy, whereas temperature is more concerned with molecular kinetic energy . Heat is the transfer of thermal energy, whereas temperature is a property the object exhibits.
