Document Summary

Physical properties: describes a substance without referring to another substance: weight, volume, boiling point. Chemical property: how a substance behaves when it reacts with another. Matter: has mass and takes up space: solid: has a defined shape and volume, liquid: in volume, has a shape of its container, gas: no defined shape or volume. Temperature: how cold or hot something is: celsius or fahrenheit. Light is a continuous wave and consist of energy particles. Visible light ranges from red to violet on the electromagnetic spectrum. Wavelength: crest to crest or trough to trough. Frequency: number of crests or crests in a given time. Refraction: the bending of light waves due to a change in velocity when light passes from a medium to another: velocity of light in a vacuum / velocity of light in the medium being examined. When tempered glass cracks, it shatters into smaller pieces that are uniform in size with smooth edges which makes them safer.
