QuestionAnswer
atom basic building block of all matter
collision Theory this qualitatively explains how chemical reactions occur and why reaction rates differ for different reactions. A basic principal is that, in order to react, molecules must collide.
conduction this is heat or electrical transfer by contact
conservation of energy this law states that, in any process, energy is neither created nor destroyed. It can only be converted from one form to another.
convection this is heat transfer due to differences in density
electrical energy energy created by the flow of electrons through a conductor.
energy the capacity for doing work. It may be transformed from one form to another.
energy transformation this is the process of changing energy from one form to another. Solar energy is changed into chemical by plants.
gas this is the phase of matter with no fixed shape or volume.
heat the transfer of thermal energy between two bodies which are at different temperatures. The SI unit for this is the Joule. Generally considered the raising of temperature due to thermal energy.
heat energy this is the form of energy that is transferred because of a difference in temperature
height this is the measurement from bottom to top of something. How tall something is.
kinetic energy this is the energy of motion
light energy energy in the form of electromagnetic radiation. Most often associated with a wavelength that is visible to the eye.
liquid this is the phase of matter with no fixed shape but fixed volume
mass this is the measure of the quantity of matter
mechanical energy the energy transferred by a force to a moving object
molecular motion this is the speed at which molecules or atoms move dependent on temperature and state of matter
pendulum this is the body suspended from a fixed support that swings freely back and forth under the influence of gravity
potential energy energy that is stored
radiation heat transfer by electromagnetic waves
speed this is the rate of distance traveled per unit of time, without regard to direction
system this is a group of related parts that move or work together forming a unified whole
thermal energy random kinetic energy possessed by objects in a material at finite temperature. An object that feels hot has a lot of this.
