Anything that has mass and takes up space
Definite shape and volume
A state of matter that has a definite volume but no definite shape.
A state of matter with no definite shape or volume
A fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors
A liquid's resistance to flowing
The uneven forces acting on the particles of a liquid's surface
A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern
Explain how matter changes from one state to another
The particles must either get faster, or slow down.
Particles of a solid
Packed tight & moving very little
Particles of a liquid
Are free to move in a container but remain in close contact with one another
Particles of a Gas
Move fast enough to overcome the attraction between them. The particles move independently of one another
Particles of Plasma
Made up of electrically charged particles, which move faster than those of a gas, and bounce randomly.
Capacity to do work or to produce heat
A measure of the average kinetic energy of the particles in an object.
The flow of energy between objects from a warmer object to a colder object.
The temperature at which a solid becomes a liquid.
The temperature at which a liquid becomes a solid.
The change of state from a liquid to a gas
The change from a gas to a liquid
Amount of heat needed to raise the temperature of 1g. of a substance 1 degrees Celsius.
When the surface particles of a solid gain enough energy that they form a gas
Vaporization at the surface of a liquid
Vaporization below the surface of a liquid.
Equals force exerted on a surface divided by the total area over which pressure is exerted.
Upward force exerted on an object immersed in a fluid
Mass / Volume
states the buoyant force on any object is equal to the weight of liquid that the object displaces.
Pressure applied to a fluid is transmitted unchanged throughout the fluid
As Altitude increases, air pressure ________
Decreasing volume _________ pressure.
Increasing temperature ________ pressure.
