Heat, Temperature, Enthalpy

Postby Wendy 1E » Wed Jan 29, 2020 7:11 pm

Can someone explain the difference between heat, temperature, and enthalpy? Thank you!

I'm not sure what exactly will answer your question, but--
Heat can be used in regards to the generality of heat transfer as a whole, what kind of reaction it is (endo or exo) and if the reaction needs heat in regards to something like a combustion
Temperature is more of the temperature a reaction is set to, the measure of how hot something is or needs to be in order to work
Enthalpy is the designated heat transfer degree for an element or bond. This is equal to the internal energy of the system plus the product of pressure and volume
hope that helps!

Heat is in a thermodynamical sense, is the energy transferred as the result of a temperature difference. Temperature is just a property of matter that lets us know like the quantity of energy in motion, and enthalpy tells us how much work or energy was added or removed from a substance or system

Enthalpy is the amount of heat absorbed or released during a reaction. Heat is the transfer of energy caused by a temperature difference that occurs in a system; and temperature represents the random motion of particles

Does anyone have a direct example from the textbook to illustrate this?
