Energy and States of Matter #1
The energy an object has due to its motion.
Kinetic Energy
Matter with a composition that is always the same.
Substance
A decrease in a volume as its temperature decreases.
Thermal Contraction
The movement of particles from an area of higher concentration to an area of lower concentration.
Diffusion
The change of state from a gas to a liquid.
Condensation
The measure of the kinetic energy of the particles in a materials.
Temperature
A substance made of only one type of atom.
Element
An increase in a volume as the temperature increases.
Thermal Expansion
The study of heat.
Thermodynamics
The change of state from a liquid to a gas.
Vaporization
Stored energy due to the interactions between particles or objects.
Potential Energy
A type of substance that occurs when atoms of two or more different elements are bonded together.
Compound
The transfer of thermal energy from a region of higher temperature to a region of lower temperature.
Heat
The increase in volume of a material when particle motion increases.
Thermal Expansion
Stored energy due to the interactions between particles or objects.
Potential Energy
The result of the motion of all the particles, and the distance and attractions between those particles in the system.
Thermal Energy
A group of chemical symbols and numbers that represent the elements and number of atoms of each element that make up a compound.
Chemical Formula
The amount of force per unit area applied to an object's surface.
Pressure
This happens when the particle motion decreases and causes the particles to occupy less volume.
Thermal Contraction
True or False:
Forces between particles increase as the particles move faster and farther apart.
False
A small particle that is the building block of matter.
Atom
Can you see an atom with a magnifying glass?
No, they are too small.
A change in state from a liquid to a gas.
Vaporization
When temperature increases, average ____________ increases.
Kinetic Energy
The evaporation of water is an example of a change of _____________________.
