Webthermodynamics, science of the relationship between heat, work, temperature, and energy. In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another. The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work. Heat was not formally … WebTemperature (in kelvin) is a measure of the average kinetic energy of molecules in an object. Heat is like mechanical work, in that an object cannot possess heat, but rather is acted upon by heat, changing the internal energy of the object. should i work out in the morning or at night
