16 kwi 2019 · Thermal energy is due to the random motions of atoms, molecules, or ions in a substance. The temperature of an object is a measure of the amount of thermal energy it contains. Heat (q) is the transfer of thermal energy from a hotter object to a cooler one.
Physics. Light Sources. When we look at a leaf we know that it is green because light bounces off the leaf to our eyes to tell us that it is green. But what is light? Which are the sources of light from which light originated? Light is electromagnetic radiation.

Learning Objectives. By the end of this section, you will be able to: Describe how the body regulates temperature. Explain the significance of the metabolic rate.
10 kwi 2024 · The chemical energy in food is converted into thermal energy through metabolism; light energy is converted into chemical energy through photosynthesis. Another example of energy conversion occurs in a solar cell.
Heat is the flow of energy from one object to another. This flow of energy is caused by a difference in temperature. The transfer of heat can change temperature, as can work, another kind of energy transfer that is central to thermodynamics.
