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.
Any sample of matter has mass and takes up space. The main reason for this is because:
All matter is heavy
Matter can be a gas
Matter is made up of tiny particles that have mass and take up space
The Earth is made of matter
If you put food coloring in room temperature water, the coloring spreads throughout the water. The water causes the color to spread mainly because:
Water molecules are warm
Water molecules are in motion
Water is more dense than food coloring
Food coloring molecules are small
Food coloring spreads out faster in hot water than in cold water. This is mainly because:
The water molecules in hot water move more quickly
The molecules in hot water are larger
The food coloring molecules are small
Hot water is less dense
When a thermometer is heated, the red liquid inside the thermometer moves up. This is mainly because:
The red liquid is thin.
The molecules of the liquid move faster and get a little further apart
The molecules of the liquid move slower and get a little closer together
The red liquid is thick
When a thermometer is cooled, the red liquid inside the thermometer moves down. This is mainly because:
Cold liquids sink
The glass of the thermometer gets cold
The molecules of the liquid move slower and get a little closer together
The red liquid is thick
When you heat a sample of a solid, the sample gets a little bigger. This is mainly because:
Heating helps the particles vibrate
Heating helps the particles stop moving
Heating helps the particles stick together
Heating helps the particles slide past each other
When you heat a sample of gas, what happens to the particles that make up the gas?
The particles move faster
The particles break apart
The particles get smaller
The particles become more dense
To describe a liquid, you could say:
The particles of a liquid are somewhat attracted to one another
The particles of a liquid are in motion
The particles of a liquid are able to move past one another
A liquid has mass and takes up space
To describe a gas, you could say:
The particles are very attracted to each other
The particles are not very attracted to each other
The particles are close together like a liquid
The particles of a gas are further apart than the particles in a liquid or solid
A ____________ in the speed of the molecules allows the attractions between molecules to bring them a little closer together.
increase
decrease
Cooling a solid _________ the motion of the atoms.
