Science Density 8th Grade

Front

How do you find the density of a solid (non-unique shape)?

Back

1. Measure Length, Width, Height of the object. 2. Multiply L*W*H using cm³ for units. 3. Measure mass using a scale. 4. Use the density equation (Density = Mass/Volume).

Front

Which state of matter is the most dense?

Back

Solids are the most dense out of all three states of matter.

Front

What are the units for the density of a liquid?

Back

g/mL.

Front

Is density a physical or chemical property?

Back

Density is a physical property.

Front

What are the units for the density of a solid?

Back

g/cm³.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

How do you measure the volume of an irregular solid?

Back

Use water displacement: Record initial water volume, submerge the object, and find the difference.

Front

What is the relationship between mass and volume in density?

Back

Density is the ratio of mass to volume; as mass increases, density increases if volume remains constant.

Front

What happens to the density of a substance when it is heated?

Back

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

Front

How does the density of water compare to that of ice?

Back

Ice is less dense than water, which is why it floats.
