Temperature Scales & Density
This video compares the Celsius and Fahrenheit temperature scales, and explains that the boiling point of water is 212° Fahrenheit and 100° Celsius, and the freezing point of water is 32° Fahrenheit and 0° Celsius.
This video outlines the following conversions: Fahrenheit to Celsius and vice versa, and Celsius to Kelvin and vice versa. It also covers the temperature at which Celsius equals Fahrenheit, and absolute zero.
This video compares the boiling and freezing points on the Fahrenheit, Celsius, and Kelvin scales. It also describes how to convert between these temperature scales.
This video defines boiling point elevation as the raising of a solvent's boiling point due to the addition of a solute, and freezing point depression as the lowering of a solvent's freezing point due to the addition of a solute. As the boiling point of a solvent increases, its freezing point decreases.
This video provides examples and practice problems on boiling point elevation and freezing point depression. In addition, this video also shows how to determine which solution will have the highest boiling point.
This video explains the difference between intensive properties and extensive properties. Intensive properties do not depend on the quantity of matter (i.e. density). Extensive properties do depend on sample size (i.e. volume, mass, etc.).
This video provides an explanation of the definition of density (density = mass/volume) using a visual aid: a density triangle.
This study guide provides an introduction to density, determining density, calculating specific gravity, and the uses of density in the geosciences.
