Heat

What is heat?

• A type of energy that can be moved from one thing to another at the same temperature.

• Matter that can be moved from one thing to another at diffrent temperatures.

• A type of energy that can be moved from one thing to another at different temperatures.

• Matter that can be moved from one thing to another at the same temperature.

• Temperature

How does heat move through matter?

• When heat touches only electrons, that makes other electrons move. When only electrons start moving, they crash into other electrons, that makes electrons only move as well.

• When matter (that you can touch) touches heat, that makes heat move. When heat starts moving, they crash into other heat, that makes them move as well.

• When heat touches electrons, it cuts through all the matter until the heat energy reaches the end of the object.

• When heat touches matter (that you can touch), that makes atoms and molecules move. When atoms or molecules start moving, they crash into other atoms/molecules, that makes them move as well.

What are the effects of combining warmer objects and cooler objects?

• The source of heat ALWAYS has to be touching the cooler object in order to speed up the molecules of the cooler object which makes the cooler object hotter. If not, the source of heat will cool down.

• When the warmer object radiate/convect/conduct a cooler object, the molecules of the cooler object speeds up, which makes the cooler object get hotter.

• When both objects meet, they both either cool or warm to the average temperature of both the cooler and warmer object.

• When the cooler object radiate/convect/conduct a warmer object, the molecules of the warmer object slows down, which makes the warmer object get colder.
