This scientific law describes the relationship between temperature and volume (as temperature increases, volume increases provided pressure remains constant)
Charles' Law
The scientific study of what matter is made of and how it chnaages is known as what?

Solid
What is the type of mixture that is made of different types of materials that can be easily distinguishable?
Heterogeneous Mixture
During a physical change, the total __________ of matter is conserved.

The ability of a fluid to exert an upward force on an object immersed in it. This is what causes objects to float.
Buoyancy
All of the atoms of an element are what?
identical
This state of matter has an indefinite shape and an indefinite volume.
Gas

Homogeneous Mixture
What is the characteristic of a material that you can observe without changing the substance?
A Physical Property
This principle tells use that as velocity of a fluid increases, the pressure exerted by the fluid decreases.
Bernoulli's principle
Describe a molecule.
Molecules form when atoms join together with other atoms.
