WebApr 6, 2024 · -Heat is the energy associated with random particle motion, while work is the energy associated with ordered one-way motion. As a result, heat is "low-quality" energy … WebLet’s look at what they actually represent. Heat is the total energy of the motion of the molecules of a substance, whereas temperature refers to the measure of the average energy of the motions of the molecules in the substance. The heat is dependent on factors like the speed of the particles, the size of the particles and the number of ...

WebSep 11, 2024 · Both heat and work are means of energy transfer. The main differentiating factor is heat is energy transfer driven solely by temperature difference whereas work is energy transfer driven by force acting through a distance. For example, The way in which entropy is defined is a very good way to differentiate between work and heat. WebApr 6, 2024 · The Carnot efficiency specifies the maximum amount of work that can be done with heat. -Heat is the energy associated with random particle motion, while work is the energy associated with ordered one-way motion. As a result, heat is "low-quality" energy and work is "high-quality" energy, which confirms the Second Law's entropy argument. WebAnswer (1 of 5): U = W + Q (first law of thermodynamics) * U is internal energy (J) * W is work (J) * Q is heat (J) The internal energy is one of the energy state functions (meaning that its value only depends on the state variables, not the process that happened). Thus, you can express the a... film developing in greensboro nc
