It … Nettet5. nov. 2024 · Since heat is a form of energy, its SI unit is the joule. Other common units of heat energy include the calorie and kilocalorie, equal to 4.186 and 4,186 joules, … Nettet8. okt. 2024 · In fact, Joule was able to show that the mechanical work has the same effect as giving heat. He found that to raise 1 g of an object by 1°C, 4.186 J of energy is required. In earlier days the heat was measured in calorie. 1Cal = 4.186 J. This is called Joule’s mechanical equivalent of heat. the plot of the lightning thief
