Heat, Work, and Internal Energy. Heat and work are energy transferred to or from a system. An object never has “heat” or “work” in it; it has only internal energy. A system is a set of particles or interacting components considered to be a distinct physical entity for the purpose of study.
Potential Energy – the separation between the particles. Internal Energy – the sum of Kinetic Energy and the inter-particle potential energy. Heat transferred between a hot and a cold body increases the internal energy of the cold body. Work done on particles increases the potential energy.
Instructions: (1) Read the problem and answer choices carefully (2) Work the problems on paper as needed (3) Pick the answer (4) Go back to review the core concept tutorial as needed. Match the thermodynamics laws (Zeroth, First, And Second) with the following statements: Energy is never created or destroyed.
Heat is the energy transferred from one object to another as the result of a temperature difference between them. Temperature is a measure of the kinetic energy of a molecular motion. Energy is the capacity to do work or supply heat. Work is defined as the distance moved times the force that opposes the motion (w =.
