Science: Density and Volume

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) or kilograms per cubic meter (kg/m³).

Front

How do you calculate the volume of an irregular object?

Back

The volume of an irregular object can be calculated using the water displacement method, where the object is submerged in water and the volume of water displaced is measured.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the metric unit for measuring volume?

Back

The metric unit for measuring volume is liters (L) or milliliters (mL).

Front

What instrument is used to measure mass?

Back

A triple beam balance is commonly used to measure mass.

Front

What is the relationship between mass and volume in terms of density?

Back

As mass increases while volume remains constant, density increases; conversely, as volume increases while mass remains constant, density decreases.

Front

What is the significance of the density of a substance?

Back

The density of a substance helps determine whether it will float or sink in a fluid, as substances with lower density than the fluid will float.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

Front

Which liquid has the highest density: water, corn oil, or mercury?

Back

Mercury has the highest density among the three.

Front

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

Back

Generally, the density of a substance decreases when it is heated, as the volume increases while mass remains constant.
