Anything that has weight and takes up space
matter
The ability of matter to dissolve in something else
solubility
The characteristics that we use to describe matter, for example: color, texture, flammability, magnetism, reactivity, toxicity, etc.
properties
Matter is made of _________ that are too small to be seen.
atoms (particles)
The smallest possible units of matter
particles (atoms)
Particles are always moving. True or False?
True, depending on the amount of energy they have some move faster than others.
Name the 4 states of matter.
liquid, solid, gas, plasma
Matter in this state has a definite shape, a definite volume, and can't be compressed.
solid
For a liquid to become a solid, heat energy needs to be: added or removed?
Removed! The temperature needs to be colder.
The amount of space that an object takes up
volume
When heat is added to a solid, it becomes this state of matter.
liquid
This type of change results in a new substance and cannot be reversed.
chemical change
Which is a change in matter that involves a change in a physical property but doesn't create a new substance?
physical change
Physical or chemical change?
physical
What happens to the particles of a liquid when we add heat/ energy?
The particles move faster and spread out more, it turns into a gas.
Toxicity and reactivity are examples of chemical properties of matter. True or false?
True
