Density, Mass, Volume

What instrument would you use to measure the mass of an object?

• Triple Beam Balance

• Graduated Cylinder

• Thermometer

• Ruler

What is the significance of a substance's density in real-world applications?

• Density helps in identifying substances and determining their behavior in mixtures.

• Density is only important in scientific research and has no practical applications.

• Density is a measure of how much space a substance occupies, unrelated to its properties.

• Density is used solely for calculating the weight of an object.

What is the formula for calculating the volume of an irregularly shaped object using water displacement?

• Volume = Final water level - Initial water level.

• Volume = Length x Width x Height

• Volume = π x Radius² x Height

• Volume = Mass / Density

What is the density of water at 4°C?

• 0.5 g/mL

• 1 g/mL

• 1.5 g/mL

• 2 g/mL

What instrument would you use to measure liquid volume?

• Graduated Cylinder

• Ruler

• Thermometer

• Barometer

What is the unit of measurement for density in the metric system?

• g/mL

• kg/m³

• g/cm³

• kg/L

What happens to the density of a gas when it is compressed?

• The density of a gas decreases.

• The density of a gas remains the same.

• The density of a gas increases.

• The density of a gas becomes zero.

How can you determine if an object will float or sink in water?

• If the object's density is less than 1 g/mL, it will float; if greater, it will sink.

• If the object is made of wood, it will float regardless of density.

• If the object is small, it will float; if large, it will sink.

• If the object is shiny, it will float; if dull, it will sink.

How does temperature affect the density of a substance?

• Generally, as temperature increases, density decreases due to expansion.

• As temperature increases, density increases due to contraction.

• Temperature has no effect on the density of a substance.

• Density remains constant regardless of temperature changes.

What is the relationship between mass, volume, and density?

• Density is the ratio of mass to volume.

• Density is the product of mass and volume.

• Mass is equal to the volume divided by density.

• Volume is the difference between mass and density.
