• mass
• volume
• weight
• length

Mass and weight are different because

• mass measures the force of gravity on an object.
• weight measures the force of gravity on an object.
• weight measures the amount of matter an object contains.
• mass measures the amount of matter an object contains.

The amount of space an object takes up is its

• volume
• density
• mass
• length

To calculate the density of an object, you would

• divide its mass by its length
• divide its volume by its mass
• divide its mass by its volume
• multiply its mass by its volume

The official SI unit of temperature is

• the metric degree
• Celsius
• Fahrenheit
• Kelvin
