Name 4 physical properties of a solid. (Hint: Think how you can describe a solid)
What are color, texture, hardness, odor, luster
100
What happens to solids, liquids, and gases when they are heated?
What is they take up more space or expand.
200
This state of matter has a definite volume but no definite shape.
What is a liquid
200
What is it called when you add heat to a solid and the solid turns to a liquid?
What is melting.
200
This part of the atom contains the proton and the neutron together in the middle of the atom.
What is the nucleus.
200
Will all liquids mix together, or will some stack on others with lesser density?
What is no all liquids do not mix together. Some can stack on others with lesser density.
200
What happens to solids, liquids, and gases when they are cooled?
What is they contract or the molecules more closer together.
300
This state of matter has no definite volume or shape.
What is a gas.
300
What is it called when you add heat to a liquid rapidly and it turns into a gas?
What is boiling
300
How many atoms are held together in a molecule?
What is two or more.
300
What is surface tension? What is an example of surface tension in nature?
What is the force of attraction of molecules of a liquid for each other. Mosquitos on a pond.
300
Dry ice changes to a gas by?
What is sublimation.
400
These are the smallest particles that make up matter.
What are atoms.
400
What happens when particles lose energy and move closer together so that a gas changes to a liquid in the form of water droplets?
What is condensation
400
What makes a compound different from a molecule?
What is a compound is made up of two or more elements.
400
What is an example of capillary action in nature? Why is this important?
What is water going from the roots of the plant to the leaves. Water will be drawn uphill and attract to other water molecules.
400
This compound lowers the freezing point of water.
What is salt.
500
Particles in a solid are? Particles in a liquid are? Particles in a gas are? (Move slowest, Move faster, move fastest) (Most closely packed, father apart, farthest apart)
Particles in a solid move slowest and are the most closely packed. Particles in a liquid move faster, and are father apart than a solid. Particles in a gas move the fastest, and are the farthest apart.
500
What happens when even more energy is taken out of a liquid and the liquid turns to a solid?
What is freezing.
500
Is water a compound or a molecule, or both? Why?
What is both. It is a molecule because it is made up of two or more atoms. It is a compound because those atoms are of different elements.
500
What happens to gas molecules in a container?
What is they move freely to fill a container of any size.
500
The changes in the states of matter are really the changes in the way ____________ move.
What is molecules.
