Temperature can change a substance's state from:
solid to liquid
liquid to gas
solid to gas
True or False:
Pressure is the amount of force exerted by molecules on a given area.
True
False
What are the three main states of matter?
Solid
Liquid
Gas
Identify matter based on these properties:
Keeps its shape and volume; particles vibrate in place
solid
liquid
gas
Identify matter based on these properties:
Takes on shape of its container
Can flow
Particles move even faster and can overcome some of the attraction between them
solid
liquid
gas
Identify matter based on these properties:
Takes on shape and volume of its container.
Particles of a substance move fastest.
Able to overcome the attraction between them and separate entirely.
solid
liquid
gas
The four types of process change are:
Melting
Vaporization
Freezing
Condensation
Which Process Change is this?
Change from solid state to liquid state. When a solid is heated the particles in that solid will begin to move faster and eventually the motion will become great enough to overcome the attraction that locks the particles together.
Melting
Freezing
Vaporization
Condensation
Which Process Change is this?
Change from liquid state to solid state. If you cool a liquid the particles will begin to slow down and eventually the motion of the particles will slow to the point where they cannot overcome the attraction between them.
Melting
Freezing
Vaporization
Condensation
Which Process Change is this?
Change from liquid state to gaseous state (water vapor), Temperature at which a liquid boils is the boiling point (100C). When a substance is heated its particles begin to move faster and faster. The fastest particles are able to overcome the attraction of the particles around them and break free completely.
Melting
Freezing
Vaporization
Condensation
Which Process Change is this?
Change from gaseous state to liquid state, Temperature at which a gas condenses is the condensation point (100C). As vapor cools, its particles begin to slow down. Condensation takes place when the particles slow down so much that they cannot overcome the attraction of the particles around them and then they clump together and form a liquid.
Melting
Freezing
Vaporization
Condensation
The total amount of kinetic energy contained in all the particles of a substance.
Kinetic energy
Thermal energy
Nuclear energy
Potential energy
Energy an object has because of its position or shape.
Kinetic energy
Thermal energy
Nuclear energy
Potential energy
Energy contained in the nuclei of atoms.
Kinetic energy
Thermal energy
Nuclear energy
