Density, Convection & Properties of Water

Front

What is the formula for calculating the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

What is density and how is it calculated?

Back

Density is the mass per unit volume of a substance, calculated as Density = mass/volume.

Front

What is the least dense liquid commonly known?

Back

Corn Oil.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, density decreases because substances expand.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What happens to warm air in terms of density?

Back

Warm air is less dense than cool air, causing it to rise.

Front

What is the density of aluminum?

Back

The density of aluminum is approximately 2.7 g/cm³.

Front

How can you determine which of two substances is more dense?

Back

Compare their mass-to-volume ratios; the substance with the higher ratio is more dense.

Front

What is the relationship between mass, volume, and density?

Back

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

Front

What is the significance of the density of water?

Back

Water has a density of 1 g/cm³ at 4°C, which is a reference point for comparing densities of other substances.
