MEASURING TEMPERATU
The temperature of any substance is directly related to the average kinetic energy (pp. 16-17) the atoms or molecules which it is made Although the lowest temperature on this thermometer -20° C (-4° F), the lows possible temperature (called absolute zero) about -273° C (-459° F This temperature occur only when atoms an molecules have no kinetic energy, or motion, at all Celsius (C) and Fahrenheit (F) are the most commonl used scales of temperature
