General physics
phase change
Physics; General physics
The action of a substance changing from one state of matter to another; a phase change always absorbs or releases internal potential energy that is not associated with a temperature change.
element
Physics; General physics
A pure chemical substance that cannot be broken down into anything simpler by chemical or physical means; there are over 100 known elements, the fundamental materials of which all matter is made.
phases of matter
Physics; General physics
The different physical forms that matter can take as a result of different molecular arrangements, resulting in characteristics of the common phases of a solid, liquid, or gas.
energy
Physics; General physics
The capacity of a body to do work is called its energy. Energy is a scalar quantity. The SI unit of energy is Joule.
absorptance
Physics; General physics
The ratio of the total absorbed radiation to the total incident radiation.
acceleration due to gravity
Physics; General physics
The acceleration imparted to bodies by the attractive force of the earth or any other heavenly body.
