Density G8

What is the definition of density?

• Density is a measure of weight per unit volume.

• Density is a measure of volume per unit mass.

• Density is a measure of mass per unit volume.

• Density is a measure of temperature per unit volume.

How do you calculate density?

• Density = Volume / Mass

• Density = Mass / Volume

• Density = Mass x Volume

• Density = Weight / Volume

What are the units commonly used to express density?

• m/s^2

• g/cm^3 or kg/m^3

• N

• L

If an object has a density greater than 1 g/cm^3, will it sink or float in water?

• hover

• disappear

• float

• sink

A block of wood has a mass of 500g and a volume of 250cm^3. What is its density?

• 2g/cm^3

• 3g/cm^3

• 1.5g/cm^3

• 0.5g/cm^3

Which has a higher density: a block of iron or a block of wood of the same size?

• block of air

• block of plastic

• block of water

• block of iron

How does the density of a gas compare to the density of a liquid or solid?

• The density of a gas varies depending on the temperature.

• The density of a gas is equal to the density of a liquid or solid.

• The density of a gas is higher than the density of a liquid or solid.

• The density of a gas is lower than the density of a liquid or solid.

Why is density an important concept in various fields such as engineering and chemistry?

• Density provides valuable information about the physical properties and behavior of substances.

• Density is only relevant for theoretical calculations, not real-world scenarios.

• Density has no practical applications in engineering or chemistry.

• Density is a concept that is easily disregarded in scientific fields.
