MEASURING THE MOVEMENT OF MOLECULES HEAT AND TEMPERATURE MEASURING THE MOVEMENT OF MOLECULES

HOW FAST ARE THE MOLECULES MOVING? 1). HOW FAST OR HOW SLOW THE MOLECULES ARE MOVING DETERMINES THE STATE OF MATTER! 2). ICE-WATER-WATER VAPOR. ADDING HEAT SPEEDS UP THE MOLECULES. TAKING HEAT AWAY SLOWS DOWN THE MOLECULES.

TEMPERATURE SCALES FAHRENHEIT-WATER FREEZES AT 32 DEGREES, AND BOILS AT 212 DEGREES. ABSOLUTE ZERO = -359 CELSIUS-WATER FREEZES AT 0 DEGREES, AND BOILS AT 100 DEGREES. KELVIN-0 DEGREES ON THE KELVIN SCALE = ABSOLUTE ZERO.

ABSOLUTE ZERO THE TEMPERATURE AT WHICH ALL MOLECULAR MOTION STOPS. THIS CAN ONLY BE REACHED IN DEEP OUTER SPACE.
