Unit 2 Exam Review Measurement

Front

What is the measurement on a triple-beam balance?

Back

A triple-beam balance is used to measure the mass of an object in grams. For example, if the measurement reads 335g, that is the mass of the object.

Front

Convert 4 cm to mm.

Back

4 cm = 40 mm (1 cm = 10 mm, so 4 cm x 10 = 40 mm).

Front

What density will allow an object to float on water?

Back

An object will float on water if its density is less than 1 g/cm³. For example, a density of 0.7 g/cm³ will float.

Front

How do you calculate density?

Back

Density is calculated using the formula: Density = Mass / Volume. For example, if an object has a mass of 4g and a volume of 2cm³, its density is 2 g/cm³.

Front

True or False: The density of a specific type of material never changes.

Back

True. The density of a specific material is a characteristic property and does not change.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in grams (g) or kilograms (kg).

Front

What is volume?

Back

Volume is the amount of space an object occupies, measured in cubic centimeters (cm³) or liters (L).

Front

What is the relationship between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass. Weight = Mass x Gravity.

Front

How do you convert grams to kilograms?

Back

To convert grams to kilograms, divide the number of grams by 1000. For example, 1000g = 1kg.

Front

What is the unit of density?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
