Test 2: Matter & Materials Flashcards
Name the 3 states matter can be in
Solid, liquid, gas.
Define matter
Everything around us that takes up space & has mass
Describe the differences between the 3 states of matter in terms of their shape
Solid: fixed. Liquid: not fixed. Gas: takes up space, but doesn’t have shape
Describe the differences between the 3 states of matter in terms of how they change their shape
Solid: changes shape by force.
L: takes the shape of the container it is in eg milk in a glass.
G: moves around freely, spreads into open spaces.
Can you see some gases?
Yes
Can you smell gas?
Sometimes.
Do an experiment to prove this by farting
What happens when you melt something?
Changes solid to liquid
What have you melted in your life before? Have you ever melted something you weren’t supposed to?
Examples: butter (over popcorn)
cheese (on toasted cheese)
candle wax
Ice cream
What is evaporation? Give some examples
Change from liquid to gas.
Water in a pool or dam
Drying clothes/dishes
What does water turn into when you heat it?
Water vapor
What is Condensation? Give examples
Gas changing to liquid
Dew on grass
Water in windscreen of car
Steam from kettle
Give example of something solidifying?
Solidify: Liquid to solid.
Eg. Ice
How would you unsolidify something? What would you call that?
Heat it up eg ice, ice cream.
Melting
Describe water cycle
Clouds: condensation leads to rain (precipitation)
Snow melts -> rivers
Ocean water evaporates in sun -> into clouds
What is precipitation in the context of weather?
Water falling from the sky
