Temperature and Kinetic Energy. Temperature and Heat. This is a sample page from the course "Temperature and Heat" -- an online course (or professional development opportunity) for elementary and middle school teachers.
For more information about this course and the program to which it belongs, see the page How energy is related to temperature When we add some thermal energy to an object, what happens to it? In most cases it is directly detectable as a small increase in temperature (the exception is during a change in phase). The energy is present in the form of the kinetic energy of the tiny rapid motions of atoms and molecules. In a solid or a liquid thermal energy has several forms: The atoms are vibrating back and forth, so they have kinetic energy; but as they move they also are bumping into each other, which involves other kinds of energy. For example, in the first activity, you placed a large and a small hot rock in cold water.

In a qualitative manner, we can describe the temperature of an object as that which determines the sensation of warmth or coldness felt from contact with it.
It is easy to demonstrate that when two objectsof the same material are placed together (physicists say when they are put in thermal contact), the object with the higher temperature cools while the cooler object becomes warmer until a point is reached after which no more change occurs, and to our senses, they feel the same.

How Does the Thermometer Work? A thermometer is a device that measures the temperature of things.
The name is made up of two smaller words: "Thermo" means heat and "meter" means to measure. You can use a thermometer to tell the temperature outside or inside your house, inside your oven, even the temperature of your body if you're sick. One of the earliest inventors of a thermometer was probably Galileo. We know him more for his studies about the solar system and his "revolutionary" theory (back then) that the earth and planets rotated around the sun. Galileo is said to have used a device called a "thermoscope" around 1600 - that's 400 years ago!! The thermometers we use today are different than the ones Galileo may have used. The red colored or silver line in the middle of the thermometer moves up and down depending on the temperature.
Fahrenheit is named after the German physicist Gabriel D. The Celsius scale is named after Anders Celsius. As far as scientists know, nothing in the universe can get that cold!
