Topic 2 Flashcards
Solid
Definite shape and volume
Liquid
Indefinite shape and definite volume
Gas
Indefinite shape and volume
Viscosity
Liquid’s resistance to flow.
Surface Tension
Inward force or pull by liquid molecules towards the surface molecules.
Vibrate
Moving slightly back and forth
Crystalline
Particles in a regular repeating pattern, creates crystals.
Amorphous
Particles not arranged in a regular repeating pattern.
Thermal Energy
Total kinetic and potential energy stored in an object.
Temperature
Measure of average kinetic energy particles in an object/substance.
Melting Point
Specific melting temperature in crystalline solids.
Freezing Point
Temperature a liquid turns into a solid.
Vaporization
Change from liquid to gas.
Boiling Point
Specific boiling temperature in liquids
Condensation
Change from gas to liquid.
Sublimation
Change from solid to gas.
Thermometer
Instrument to measure temperature.
Pressure
Force of an outward push over an area.
Charle’s Law
At a constant pressure if temperature decreases then volume decreases. Temperature and volume have a direct relationship.
Boyle’s Law
At a constant temperature is the pressure increases then volume decreases. Pressure and volume have an inverse relationship.
Directly Proportional
As one variable decreases the other decreases the same rate (vice versa and applies the same to an increase).
Inversely Proportional
As one variable increases the other decreases. (vice versa).
