Which quantity is measured in kg/m³?

• Mass

• Volume

• Density

• Pressure

How do you calculate density?

• Mass × Volume

• Volume ÷ Mass

• Mass ÷ Volume

• Force × Area

A block has a mass of 200 g and a volume of 100 cm³. What is its density in g/cm³?

• 0.5 g/cm³

• 2 g/cm³

• 20 g/cm³

• 0.2 g/cm³

An object will float in water if its density is:

• Greater than 1 g/cm³

• Less than 1 g/cm³

• Equal to 1 g/cm³

• More than 5 g/cm³

What happens to the density of an object when its mass increases while the volume stays the same?

• Density increases

• Density decreases

• Density remains the same

• Density becomes zero

Which instrument is used to measure the mass of an object?

• Thermometer

• Balance

• Barometer

• Ammeter

The volume of an irregular object can be measured using:

• A graduated cylinder and the displacement method

• A ruler and measuring tape

• A thermometer

• A stopwatch

Pressure is defined as:

• Force × Area

• Force ÷ Area

• Mass × Volume

• Density × Gravity

What are the units of pressure?

• kg/m³

• N/m²

• N/kg

• J/s

Which situation results in the greatest pressure?

• Standing on sand with flat shoes

• Standing on sand with high heels

• Lying flat on the floor

• Sitting on a chair
