State of Matter 1
What is kinetic energy due to?
Motion
Which state of matter has the most kinetic energy?
gaseous
What is the measure of the average kinetic energy of all the particles in an object called?
Temperature
What is the change of state from a gas to a liquid called?
Condensation
This state of matter has definite shape and volume Definite. Particles are tightly packed and vibrate in place
Solid
A small particle that is the building block of matter
What is Atom?
Why kind(s) of energy do particles have?
Potential
Kinetic
What is it called when vaporization occurs within a liquid?
Boiling
When thermal energy is removed from water vapor, it ______ at 100 C, and the liquid water _______ at 0 C.
freezes
This state of matter has indefinite shape. Particles are close together but can slide past one another freely.
Liquid
What is it called when enough thermal energy leaves a liquid to change it from a liquid to a solid?
Freezing
How can an object's state of matter be changed using thermal energy?
Thermal energy can be added or removed.
What 3 changes affect gases more than solids and liquids?
Temperature, pressure, and volume
What is it called when vaporization occurs only at the surface of the liquid?
Evaporation
Particles are far apart and move randomly at high speeds.
Gas
What happens to potential energy as particles get farther apart?
It increases
What are always conserved during a change of state?
Matter and energy
What is the total kinetic and potential energy of an object measured by?
Thermal energy
An _____ system allows energy and matter to be released into the
Open system
What is the change of state from a gas to a solid without going through the liquid state?
Deposition
What is the process during which a liquid changes to a gas?
Vaporization
When you add thermal energy to ice, the temperature of the ice increases, which means that the ______ ______ of the water molecules increases.
Kinetic energy
What is the process that happens when enough thermal energy is added to change a solid to a liquid?
Melting
