100
The three states of matter.
What are solid, liquid, and gas?
100
The temperature at which a liquid changes to a solid.
What is freezing point?
100
This occurs to the molecules of a substance when that substance gains heat energy.
What is the molecules speed up?
100
The most common universal solvent.
What is water?
200
This part of an atom determines its position as an element on the periodic table.
What is a proton?
200
This state of matter takes the shape and volume of its container.
What is gas?
200
The change of a substance from a liquid to a gas.
What is evaporation?
200
The energy in water does this when an ice cube tray is placed in the freezer.
What is loses energy?
200
This is a substance that dissolves in a liquid.
What is solute?
300
The three particles that make up an atom.
What are protons, neutrons, and electrons?
300
This state of matter has a definite shape and a define volume.
What is solid?
300
This must occur to change solid ice to liquid water.
What is add heat to the water molecules?
300
The molecules of water in a heated pot do this.
What is move faster and spread apart?
300
This is the liquid in which something dissolves.
What is solvent?
400
Atoms with the same number of protons.
What is an element?
400
This state of matter is between its boiling point and its freezing point.
What is liquid?
400
This occurs when a cup of cold water is covered with drops of water.
What is water vapor in the air cooling and condensing onto the cold glass?
400
This is what happens to the molecules of a substance at its boiling point.
What is move independently from each other and spread apart?
400
The equation for density.
What is mass divided by volume?
500
The atomic number of an element indicates this.
What is the number of protons in the nucleus?
500
The state of matter when a substance is above its maximum condensation point.
What is gas?
500
This change of state occurs when the body cools itself by sweating.
What is evaporation?
500
Three methods to cause the molecules in a cup of water to move QUICKLY.
What is heating the water, stirring the water, and swirling the water? (answers may vary)
500
