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.
Thermal energy is also known as internal kinetic energy.The transfer of thermal energy from one body to another is the result of temperature variations. Heat moves along areas of higher temperature to areas of lower temperature. The three mechanisms for heat transfer include conduction, convection and radiation.
