Particles packed tightly together, vibrate in place. This gives it a definite shape and definite volume.
What is a solid?
100
What must be added or removed from any substance to change it from one state to another.
What is heat (thermal energy)?
100
Amount matter in an object. Measured in grams (kilogram = 1,000 grams).
What is mass?
100
How easily a liquid flows. You might also call it the resistance to flowing.
What is viscosity?
100
The most basic building blocks of all matter that make up elements.
What are atoms?
200
Particles are moving rapidly and bouncing off each other and off the walls of the container they are in. This gives it an indefinite shape and an indefinite volume.
What is a gas?
200
Changing from a solid to a liquid.
What is melting?
200
Measure of the force of gravity acting on an object. Measuring in pounds (lbs.) or ounces (oz.).
What is weight?
200
How well a material allows electricity or heat to flow through it?
What is conductivity?
200
Chart that organizes the elements based on their properties.
What is the periodic table?
300
Particles are close, but are free to flow and move around one another. This gives it a definite volume, but an indefinite shape.
What is a liquid?
300
Changing from a liquid to a solid.
What is freezing?
300
Amount of space (3D) an object occupies.
What is volume?
300
The measure of the average energy of motion of the particles in a substance.
What is temperature?
300
Elements combine to form these. For example, water is hydrogen combined with oxygen.
What is a compound?
400
The state of matter that has the highest thermal (kinetic) energy.
What is a gas?
400
Changing from a liquid to a gas. Both ways.
What is evaporation or boiling?
400
How much mass is in a given volume. In other words, mass divided by volume. Determines floating and sinking.
What is density?
400
When a solid changes directly into a gas. Water does this some, but we don't notice when some of the snow just goes straight to water vapor. Dry ice is solid carbon dioxide and it does this noticeably.
What is sublimation?
400
All living and non-living materials are made of these.
What are atoms (or elements)?
500
The state of matter with the least kinetic (thermal) energy.
What is a solid?
500
Changing from a gas to a liquid.
What is condensation?
500
Measure of how much of a substance dissolves in a solvent, such as water.
What is solubility?
500
The 1) freezing/melting point of water and 2) the boiling point of water. Show on both temperature scales.
What is 1) 32 degrees F or 0 degrees C and 2) 212 degrees F or 100 degrees C.
500
When atoms in a solid 1) arrange into a regular pattern (examples would be salt or quartz) or 2) do not form any pattern (like butter or chocolate).
What are 1) crystals (crystalline) and 2) amorphous?
