- Tension Force
- A force that is applied in such a way as to stretch a material.
- Solid
- A physical state of matter that is characterized by the rigidity and resistance to changes in size and shape.
- Ionic Conductors
- Materials that do not conduct electricity in the solid state, but do when molten or dissolved in water.
- Non-Conductor
- A material which does not conduct electricity in any of its physical states.
- Gas
- A physical state of matter that readily changes both shape and volume to match its container.
- Compression Force
- A force that is applied in such a way as to compress a material.
- Supercritical Fluid
- Has the property of filling the volume of its container like a gas, but dissolving materials like a liquid.
- Plasma
- A physical state of matter characterized by fluid properties in which positive and negative charges move independently.
- Shear Force
- A force that is applied in such a way as to twist or deform a material.
- Liquid
- A physical state of matter that readily changes shape to match its container but that resists change in volume.
- Electromagnetic Spectrum
- The entire range of radiation including in order of decreasing frequency, cosmic-ray photons, gamma rays, x-rays, ultraviolet radiation, visible light, infrared radiation, microwaves, and radio waves.
- Continuous Spectrum
- A spectrum in which the colors blend gradually together without noticeably abrupt changes or missing colors.
- Conductors
- Materials that conduct electricity in the solid and liquid state.
- Discrete Spectrum
- A spectrum of separate and distinct colors in which not all colors are present.
