States of Matter
The three states of matter
The definition of Density
Solubility is
What is the ability for one object to dissolve in another
What is when something changes a state.
(Liquid to solid)(Solid to liquid)
(Liquid to gas)
What is a change in the size, shape, or state of matter.
What is less dense, corn syrup or a lego?
What is a lego?
You can speed up the solubility of a substance by
What is by raising the temperature of the solvent?
What happens to the particles in an ice cube as the ice cube melts
What is they begin spreading farther apart and sliding past each other.
A chemical change is
What is when particles of a substance are changed into a new substance?
Particles in a liquid
What are not as tightly packed together as a solid and are able to move over each other when moving (poured).
An object's density determines
What is whether an object sinks or floats in a liquid?
How can water change phases?
what is going from a liquid to a solid, a solid to a liquid, or a liquid to a gas
An example of a physical change is
What is a log burning, and pencil breaking, or paper ripping.
Particles in a gas
What are spread very far apart. Gas particles are able to move in any direction and are found everywhere.
What is more dense water or a cork?
What is water?
what is zero. These two substances will not mix.
Energy can change phases when enough heat energy is added or taken away. Energy causes the particles to move faster and therefore farther apart.
An example of a chemical change
What is rust on a nail.
This is the only natural element that can be found in a solid, liquid, AND gas
What is water
What can you infer about the density of a car if it sinks to the bottom of a cup of water?
What is the car is more dense than the water it was floating in.
Sand
What is does not dissolve in water?
What is with a ruler and multiplying its length, width, and height.
When a log burns, is it a chemical or physical change?
What is a physical change. Nothing new is being added to change the make up of the log
