Matter

What is matter?

• the measure of how heavy or light something is for its size

• the force of gravity on an objects mass

• anything that has both mass and volume

• the amount of space an object takes up

What units do we use to measure mass?

• Fahrenheit or Celsius

• pounds or Newtons

• centimeters or inches

• grams or ounces

Which property of matter changes depending on the gravitational pull?

• weight

• mass

• volume

• density

Which of the following determines an object’s ability to float in water?

• how much the object weighs

• what the mass of the object is

• how dense the object is

• the volume of an object

How would you measure the volume of an oddly-shaped object, like a teacup?

• by placing it in a room without any gravity

• by placing the cup in water and measuring how high the water rises

• by placing it on a scale

• by breaking the cup into tiny pieces and placing those pieces in a beaker

What is density?

• the amount of space that an object takes up

• anything that is a solid, liquid, or gas

• the amount of matter contained in an object

• the measure of how light or heavy something is for its size

How are mass and volume alike?

• They are only found in solids.

• They are measured in grams.

• They always stay the same.

• They cease to exist when an object is placed in water.

In which state of matter are molecules moving the slowest?

• solid

• liquid

• gas

• all of the above

Which of the following causes a solid to change to a liquid?

• the freezing point

• evaporation

• cold

• heat

What point has water reached when it turns from a liquid to a solid?

• its boiling point

• its melting point

• its freezing point

• its heating point
