Any sample of matter has mass and takes up space. The main reason for this is because:
If you put food coloring in room temperature water, the coloring spreads throughout the water. The water causes the color to spread mainly because:
Food coloring spreads out faster in hot water than in cold water. This is mainly because:
When a thermometer is heated, the red liquid inside the thermometer moves up. This is mainly because:
When a thermometer is cooled, the red liquid inside the thermometer moves down. This is mainly because:
When you heat a sample of a solid, the sample gets a little bigger. This is mainly because:
When you heat a sample of gas, what happens to the particles that make up the gas?
To describe a liquid, you could say:
To describe a gas, you could say:
A ____________ in the speed of the molecules allows the attractions between molecules to bring them a little closer together.
Cooling a solid _________ the motion of the atoms.
Draw a model that shows what happens to a group of atoms/molecules when you increase the thermal energy. Annotate your model with the three atomic behaviors.
