What is Matter?
anything that has weight and takes up space
What state of matter has particles packed close together, vibrating in a fixed position?
Solid
Which state of matter is characterized by definite volume, no definite shape, takes the shape of container, has particles are tightly packed, but far enough apart to slide over one another?
Liquid
What state of matter is characterized by no definite volume, no definite shape, it takes the shape of container, and has particles are very far apart that move freely except when they collide?
Gas
What is the term for the phase change from a liquid to a gas?
Vaporization/Boiling/Evaporation
Heat Movement during condensation
Heat leaves the gas as it condenses
What is the term for the phase change of a gas into a liquid?
Condensation
What is the term for the phase change of a solid into a gas?
Sublimation
What is the term for the phase change of a solid to a liquid?
Melting
What is the term for the phase change of a liquid into a solid?
Freezing
Heat Movement during Sublimation, phase change from a solid to a gas?
Heat goes into the solid as it sublimates
What is Thermal Energy?
the energy contained within a system that is responsible for its temperature and due to the movement of the particles within
What is Expansion?
an increase in material's volume when its temperature increases.
What is Contraction?
A decrease in a material’s volume when its temperature decreases.
What is a Phase Change?
the transformation of one state of matter into another, result of adding or removing thermal energy
What is Charles’s Law?
the volume of gas increases as the temperature increases, V1 / T1 = V2 / T2
