Molecules are always moving
Measuring kinetic energy
Using thermometer as temperature
The greater the internal energy, the higher the temperature of that material
Energy flow between objects of different temperatures
Heat and temperature are not the same thing
Not the same
Describes how visible particles are seen moving due to invisible molecules bumping into them.
Matter that definite volume and shape and molecules that are packed together tightly and move slowly
Matter has definite volume but not shape and since the molecules of a liquid are loosely packed, they move faster
Matter that has indefinite volume or shape and molecules of a gas are so loosely arranged and move so rapidly that they will fit into their container
The change from solid to liquid
The change from liquid to solid
The change from liquid to gas
The change from gas to liquid
The change from solid to gas
The change from gas and solid
In which phase are molecules held rigidly together?
In which phases does the molecules move freely?
Gas, and liquid
In which are the molecules in a define shape?
In which phases do the molecules take the shape of their container?
Liquid and gas
Ice warmed to the melting point.
Vibrates more until the molecules break free
Water is to the boiling point
The molecules see moving faster bouncing around until they break
Water is cooled to the freezing point
The molecules slow up to the point they are barely moving sticking to form ice
