100

A measure of how tightly packed the atoms are in a substance

Density

100

The temperature when a liquid changes phases to a gas.

Boiling Point

100

The curved surface observed in a liquid placed in a graduated cylinder.

200

Name 3 physical properties that stay the same for a substance, regardless of the amount of matter.

Melting/Boiling/Freezing Point, Density, Solubility

200

Equation for Density

Density = Mass divided by Volume

200

The temperature when a solid changes phases to a liquid.

Melting Point

200

How can you measure the volume of an irregular shaped object using a graduated cylinder?

Record an initial water level. Drop the object in. Measure the higher level. Then subtract the low level from the high level.

300
any property of matter that can be observed by your senses
physical properties
300

How can you change the solubility of a substance?

Heat up the solvent (change temperature), stir/shake it in the solvent.

300

What must the density of an object be, in order to float in a liquid, compared to the density of the liquid?

The density of the object must be less than the density of the liquid.

300

The temperature when a liquid changes phases to a solid.

Freezing Point

300

A measurement of how much space an object takes up.

Volume

400

the smallest particle (unit) of matter

atom
400

Do you weight more or less on the moon?

Less. Gravity is 1/6th as strong on the moon, so your weight is 1/6th of your weight on Earth.

400

To make something more dense and sink, what are two things can we change about it?

Its volume or its mass. (D=M/V)

400

How do the atoms behave in a substance that is heated up?

The speed up, expand, and spread out.

400

Units on a graduated cylinder or the units used to measure volume.

mL (milliliters)

500

a measurement that indicates how heavy a person is due to gravity

Weight

500
Physical properties must be things you can ___________ using your five senses. You can not guess when describing the physical properties of an object.

500

Ice floats in water because its density is MORE or LESS than the density of water?

LESS (Less density)

500
How can you change the state of matter?
freezing, melting, increasing temperature, or decreasing temperature
