Density

Front

What is density?

Back

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

Front

What is the formula to calculate density?

Back

Density = Mass / Volume

Front

What is displacement in the context of measuring volume?

Back

Displacement is the method of measuring the volume of an irregularly shaped object by observing how much water it displaces when submerged.

Front

What tool is commonly used to measure mass?

Back

Triple beam balance.

Front

If an object has a density greater than water (1 g/mL), will it sink or float?

Back

It will sink.

Front

If an object has a density less than water (1 g/mL), will it sink or float?

Back

It will float.

Front

How do you find the volume of an irregular object using water?

Back

Submerge the object in a graduated cylinder and measure the change in water level.

Front

What is the density of an object with a mass of 10g and a volume of 5cm³?

Back

Density = 10g / 5cm³ = 2 g/cm³.

Front

What happens to the density of an object if you increase its mass while keeping its volume constant?

Back

The density increases.

What happens to the density of an object if you increase its volume while keeping its mass constant?

Back

The density decreases.
