Literature relating to the presence of ESL students in mainstream classes has suggested that some teachers view subject-related content mastery and second-language development as separate processes, with the latter seen as the responsibility of ESL-specialist teachers (Penfield, 1987).
Kinetic energy is the production of energy by an object in motion. There are three subcategories of kinetic energy, including vibrational, which is caused by objects vibrating; rotational, which is caused by moving objects; and translational, which is caused by objects hitting one another.
Heat is the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object. Such energy transfer can occur in three ways: radiation, conduction, and convection.
