Materials and their Structure Flashcards
3 groups of matter - solids, liquids, gas
States of Matter
A space where there are no particles
Vacuum
A testable theory
Hypothesis
Everything that you can see and feel
Matter
Matter that can spread out to fill all the space available but can be squashed into a smaller volume
Gas
Matter that has a fixed shape
Solid
Matter that has a fixed volume but takes the shape of its container
Liquid
Move back and forth repeatedly
Vibrate
Squashed
Compressed
The amount of space taken up by the solid, liquid, or gas
Volume
The feature of a material and how it behaves
Property
The ideas that scientists have
Theory
To pour, move smoothly
Flow
To flow from a container
Pour
Very small pieces of matter that everything is made up of
Particle
A reference line on a graph that you can measure from to find values.
Axis
Change from a gas to a liquid
Condense
Change from a liquid to a gas
Boil
The temperature at which a liquid changes to a gas
Boiling point
To change from one state to another, melt, boil, evaporate, condense, freeze
Change of state
An instrument to measure temperature
Thermometer
Change from a liquid to a gas, at a temperature below boiling point
Evaporation
Change from a liquid to a solid
Freeze
Change from a solid to a liquid
Melt
Glassware for measuring the volume of a liquid
Measuring Cylinder
The curve on the edge of a liquid
Meniscus
The temperature at which a solid changes to a liquid
Melting point
Water in the form of a gas
Water Vapour
Water vapour produced when the water boils
Steam
Forces that hold particles together
Attractive Forces
Passed from one place to another
Transferred
The energy put into a substance that causes it to get hotter
Thermal Energy
To get larger
Expand
