What are physical properties?
Characteristics that describe matter such as volume, density, mass, length, magnetism, state of matter.
100
Which state of matter has no fixed shape BUT a fixed volume?
Liquid
100
What is the phase change from solid to liquid called?
melting
100
What tool do we use to measure mass?
Pan balance OR digital scale OR triple beam balance
100
What unit do we measure mass in?
grams (g)
200
What is matter?
Anything that has mass and takes up space.
200
Which state of matter has the most compact molecules?
Solid
200
What causes molecules to move faster and spread out?
More energy
200
What tool do we use to measure volume?
beaker of graduated cylinder
200
What unit do we measure volume in?
millileters (mL) - for liquids
OR
cubic centimeters (cm3) - for solid object
300
What is density?
The ability of an object to sink or float
300
What state of matter has no fixed shape or no fixed volume?
Gas
300
What causes particles to slow down?
Removing heat energy
300
What tool do we use to test the magnetism of an object?
A magnet
300
What unit do we measure length in?
centimeters (cm)
400
What is mass?
The amount of matter in an object.
400
What are the three states of matter on Earth?
Solid, Liquid, Gas
400
What is it called to go directly from a solid to a gas (skipping the liquid phase)?
Sublimation
400
What can do we use to measure the density of an object?
water in a container
400
What unit do we measure temperature in?
Degrees Celsius
500
What physical property is being shown here?
Density
500
Which state of matter is characterized by particles with the most space between them and the most energy?
gas
500
What is the freezing point of water?
0 degrees Celsius.
500
How can we determine the state of matter of a substance?
Examine its volume and shape.
Fixed volume and shape is a solid.
Fixed volume but changing shape is a liquid.
Changing volume and changing shape is a gas.
500
What is it called when an object is NOT attracted to a magnet?
repel
