2. a current in a fluid that results from convection.
5. the reinforcement or prolongation of sound by reflection from a surface or by the synchronous vibration of a neighboring object.
6. the process by which sound waves travel through a medium.
8. Carbon dioxide, methane, nitrous oxide, water vapour
9. an object that absorbs all electromagnetic radiation that falls on it at all frequencies over all angles of incidence.
10. (chiefly of pollution or environmental change) originating in human activity.
12. energy which a body possesses by virtue of being in motion.
15. Molecular vibration can be considered to be like the motion of particles connected by springs.
17. the process in which electromagnetic radiation or particles are deflected or diffused.
18. any three-dimension species (e.g., a molecule) will have three degrees of rotational energy since it can rotation in the x, y and z axis
19. A gray body is an imperfect black body
20. an electron that is not attached to an atom or molecule and is free to respond to outside forces.

1. movement that changes the position of an object, as opposed to rotation.
3. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse.
4. the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
7. having three atoms in the molecule.
11. the balance between incoming energy from the Sun and outgoing energy from the Earth.
13. the amount of energy received by a given area one astronomical unit away from the Sun
14. (of electromagnetic radiation) having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves. Infrared radiation has a wavelength from about 800 nm to 1 mm, and is emitted particularly by heated objects.
16. the frequency or rate that it vibrates naturally when disturbed.
