What is Temperature? • Temperature is a measure of the average kinetic energy of the particles in an object.
Temperature Scales Fahrenheit °F (Typically used by Americans) Celsius °C (Used by the rest of the world) Kelvin K (Used by scientists)
Absolute Zero At absolute zero, all moving matter should stop. – 273. 15 °C - Celsius – 459. 67 °F - Fahrenheit
Temperature vs. Thermal Energy
Temperature vs. Thermal Energy • Low Temp = Slow moving particles (colder) • High Temp= Fast moving particles (hotter)
Temperature vs. Kinetic Energy

Lab Instructions
Temperature vs. Food Coloring Particles 1. Pick up a blue tub from the back table. 2. Look at the beakers labeled COLD WATER, ROOM TEMPERATURE WATER, HOT WATER. 3. Measure the temperature of each. 4. Take turns dropping ONE drop of food coloring in each beaker. 5. Do not stir or shake beakers. 6. Observe with your group which beaker the food coloring particles move the quickest in.
Let’s review… Which temperature beaker did the food coloring particles appear to spread the slowest in? Why?
