States
What is solid, liquid or gas?
A liquid changing into a solid.
What is freezing?
a substance that may look, act or feel different but its still the same thing. Changes in matter that are reversible.
Anything that has mass and takes up space.
What is matter?
When all particles are always in this constant state.
What is motion?
Has a definite shape and volume.
What is a solid?
A solid changing into a liquid.
What is melting?
When one substance changes and becomes a completely different substance. Changes are irreversible and cannot change back.
What is a chemical change?
is the smallest possible unit of matter.
What are particles?
Sun, food, water, plants/ trees.
Where does energy come from?
In what state do particles move extremely quickly and bounce off each other.
What is a gas?
A liquid changing into a gas.
Rust on a car.
What is an example of chemical change?
To do work or to cause change.
What is energy?
Kinetic and potential.
What are the two different types of energy?
Has a definite volume but not a definite shape.
What is a liquid?
A gas changing into a liquid.
What is condensation?
When energy is taken away from a liquid, the particles slow down and don’t move around so much. They settle into the lower energy solid state forming crystals.
What is freezing?
The state that occurred when we did the baking soda and vinegar experiment.
What is an example of chemical change?
What is water?
The change when we put hot water in a cup, then placed another cup on top with an ice cube at the top.
What is an example of condensation?
When we did the experiment of making jell-O.
What is an example of both physical and chemical change?
Adding energy to a solid cause the particles to move faster and faster until they can no longer stay in the structure of the crystals.
What is melting?
The state that occurred when we broke our chocolate chip cookies.
What is an example of physical change?
