Temperature Scales
Temperature Conversions • The Celsius scale is based on the freezing and boiling points of water at standard pressure.
Temperature Conversions • The Celsius scale is based on the freezing and boiling points of water at standard pressure. • The Kelvin scale has its zero at absolute zero.
Temperature Conversions • The Celsius scale is based on the freezing and boiling points of water at standard pressure. • The Kelvin scale has its zero at absolute zero. • Kelvin units and Celsuis degrees are the same size.
Temperature Conversions • The Celsius and the Fahrenheit scales are based on the freezing and boiling points of water at standard pressure. • The Kelvin scale has its zero at absolute zero and Kelvin units are the same size as Celsius degrees. • The Rankine scale has its zero at absolute zero and Rankine units are the same size as Fahrenheit degrees.

Precision and Accuracy • Precision of a measurement indicates how well several separate determination of the same quantity agree with one another. • Accuracy is how well the determinations agree with the accepted value for that quantity.
Experimental Error • Error = experimentally determined value-accepted value. • Percent error = (error in measurement)/(accepted value)
