What is a liquid?
Packed closely and slide past each other
What is a solid?
Fixed positions
What is a gas?
Constant state of motion
What is plasma?
A state of matter that starts with gas.
What is energy?
The capacity to do work.
What is thermal energy?
Kinetic energy
What is evaporation?
When a substance goes from liquid to gas.
What is sublimation?
The process in which a solid changes directly to a gas
What is condensation?
The change of a substance from gas to liquid.
What is exoteric change?
Releases the substance as it changes state.
What is Crystalline solids?
They have orderly arranged of atoms and molecules.
What is amorphous solids?
They are composed of atoms or molecules that are in no particular order.
What is surface tension?
Force acting on the particles at the surface of a liquid
What is kinetic energy?
Energy of motion
What is heat?
Temperature change in a substance.
What is a fluid?
Nonsolid state of matter.
What is a buoyant force?
The upward force on an object
What is pressure?
The amount of force exert per unit
What is Archimedes principle?
An principle that states the buoyant force on a object.
What is a pascal?
The SI unit of pressure
What is pascals principle?
The principle that states that a fluid in equilibrium.
What is viscosity?
The resistance of a gas or liquid flow.
What is Bernoulli’s principle?
States the speed of a moving object fluid increases the pressure of moving fluid decreases.
What is endothermic change?
the word describes a process that releases energy in the form of heat. Forming a chemical bond releases energy and therefore is an exothermic process.
