Alta Physics Heat Heat is a form of  Energy Transfer Heat flows from areas of high energy to  areas of lower energy Heat is transferred three way Conduction – requires contact Convection – mass movement of  molecules Radiation – transfer over a distance

Alta Physics Temperature Scales Temperature is defined as a measure of  the  average kinetic energy  of the  molecules. Temperature scales were developed  using the freezing and boiling points of  water at sea level as the standard  reference points.

Alta Physics Temperature Scales There are three Temperature Scales  used in Science Fahrenheit – Used primarily in the United  States Celsius – the standard for the Metric  System Kelvin – Also know as the “Absolute Zero”  Scale.

Alta Physics Conversion Equations Fahrenheit to Centigrade C = 5/9 (F – 32) Ex: C = 5/9 (212-32) = 100 Centigrade to Fahrenheit F = (9/5 C) + 32 Ex: F = (9/5)(100) + 32 = 212

Alta Physics Conversion Equations Centigrade to Kelvin K = C +273 Ex: K = 100 + 273 = 373 Kelvin to Centigrade  C = K - 273 Ex: K = 373 - 273 = 100
