Question

Quizplus · Accepted Answer

Internal energy refers to the total energy contained within a system. The hot pizza contains internal energy due to the heat that is stored within it, which is transferred from the oven where it was cooked. While heat is a form of energy, it is not a property or quantity of the pizza itself. Temperature is a measure of the average kinetic energy of particles within a system, but it is not a quantity that is stored within the pizza. Work is the transfer of energy between systems due to the application of force, and it is not a factor in the energy content of the pizza.
