States of Matter and Density
The state of matter has particles that are close together and vibrate in place
What is a solid?
During a phase change, this measurement stays the same even if volume changes.
What is mass?
This external force opposes motion when two surfaces touch.
What is friction?
These resources of energy can be naturally replenished if used responsibly.
What are renewable resources?
This law states that every action force has an equal and opposite reaction force.
What is Newton’s Third Law of Motion?
This property compares the mass of a substance to the amount of space it takes up.
What is density?
This is the Celsius temperature at which water melts or freezes.
What is 0°C?
This internal force squeezes or compacts an object.
What is compression?
These resources take millions of years to form and can be depleted.
What are non‑renewable resources?
When you push on a wall, the wall does this back to you.
What is “pushes back with an equal and opposite force”?
Water is unusual because its solid form has greater ______ than its liquid form, making ice less dense.
What is volume?
Water expands when it freezes, causing this change in density.
What is “solid water becomes less dense”?
This internal force occurs when different parts of an object are pushed in opposite directions, causing bending or potential breakage.
What is shear?
These four factors influence which energy resources a community chooses.
What is availability and accessibility, environmental impact, societal impact and economic impact?
When a swimmer pushes water backward with their hands, this force pushes the swimmer forward.
What is the reaction force of the water?
A substance that is less dense than the fluid it is placed in will do this.
what is float?
This forms on lakes in winter and protects aquatic life.
What is an insulating sheet of ice?
This property allows an object to return to its original shape after a force is removed.
What is elasticity?
This term describes using energy resources in ways that minimize disruption to nature and respect land rights.
What is responsible resource management?
When a person jumps off a small boat, the person moves forward. This is what the boat does in response.
What is move backward with an equal and opposite force?
This particle‑level explanation describes why gases are compressible but liquids are not.
What is “gases have large spaces between particles, while liquids have smaller spaces”?
This tool works due to expanding and contracting
What is a liquid thermometer
This internal force occurs when an object is twisted,
What is torsion?
This factor must be considered when selecting energy resources because it includes land rights, cultural values, and impacts on communities.
What is societal impact (or respect for land and resource rights)?
When a hammer strikes a nail, the nail pushes back on the hammer with this type of force.
What is an equal and opposite reaction force?
