Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

If a block is cut in half, how does its density change?

Back

The density remains the same regardless of the size of the piece; it is an intrinsic property of the material.

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the density of copper if its mass is 89g and volume is 10.0 cm³?

Back

8.9 g/cm³.

Front

What is the significance of significant figures in measurements?

Back

Significant figures indicate the precision of a measurement and help convey the accuracy of the data.

Front

How many significant figures are in the measurement 6.300?

Back

There are four significant figures.

Front

What is the volume of an object if it displaces 25.0 cm³ of water?

Back

The volume of the object is 25.0 cm³.

Front

What is the correct measurement to report from a graduated cylinder reading of 6.32?

Back

6.32 is reported with three significant figures.

Front

What is the correct measurement to report from a ruler reading of 41.6?

Back

41.6 is reported with three significant figures.

Front

What happens to the density of a substance if its mass increases while its volume remains constant?

Back

The density increases.
