What is the term for the phase change of a solid into a gas?
Sublimation
What is the Kinetic Theory of Matter?
All matter is made of tiny particles-atoms/molecules, that are in constant motion. The state of matter determines how tightly these particles are packed/bonded
What state of matter has particles packed close together, vibrating in a fixed position?
Solid
What is the term for the phase change from a liquid to a gas?
Vaporization/Boiling/Evaporation
Describe the heat movement as a liquid changes into a gas.
Heat goes into the liquid as it is vaporized
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
Particles vibrate or move around ______ if the matter is cooled.
Less
What is Matter?
anything that has weight and takes up space
What is the heat movement during the melting phase?
Heat goes into the solid as it melts
What is a System?
The set of interacting substances and energy that is being studied.
Heat Movement during condensation
Heat leaves the gas as it condenses
Heat Movement during Sublimation, phase change from a solid to a gas?
Heat goes into the solid as it sublimates
What is Expansion?
an increase in material's volume when its temperature increases.
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 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 the term for the phase change of a liquid into a solid?
Freezing
Particles vibrate or move around _______ if the matter is heated.

What is a Phase Change?
the transformation of one state of matter into another, result of adding or removing thermal energy
What is the heat movement during the phase change of liquid to a solid?
Heat leaves the liquid as it freezes
What is the term for the phase change of a gas into a liquid?
Condensation
What is Charles’s Law?
the volume of gas increases as the temperature increases, V1 / T1 = V2 / T2
What is Contraction?
A decrease in a material’s volume when its temperature decreases.
