WebThis is a result of the law of conservation of energy, which says that, in a closed system, total energy is conserved—that is, it is constant. Using subscripts 1 and 2 to represent initial and final energy, this law is expressed as. K E 1 + P E 1 = K E 2 + P E 2. Either side … WebApr 8, 2024 · There are different forms of energy in nature like mechanical energy, sound energy, light energy, electric energy, tidal energy, heat energy, etc. Heat energy is generated due to the transfer of heat from a warm system to a cool system. Heat energy is an essential form of energy in our day-to-day activities like cooking, heating, ironing, etc.
WebJan 15, 2024 · With careful measurements of the work done on a system and careful measurements of the temperature of the system he was able to show that mechanical work was proportional to heat. It turns out that this is a general principle. For example, not only mechanical work but electrical work can also change thermal energy.
