What is density?

Back

Density is the measure of how much mass is contained in a given volume. It is calculated by dividing mass by volume.

Front

What is a solution?

Back

A solution is a type of mixture where one substance (the solute) dissolves in another substance (the solvent), forming a homogeneous mixture.

Filtration is a technique used to separate solids from liquids by passing the mixture through a filter.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in grams or kilograms.

Front

What is the principle of buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which depends on the density of the object compared to the density of the fluid.

Front

What is the difference between a mixture and a compound?

Back

A mixture is a combination of two or more substances that retain their individual properties, while a compound is a substance formed when two or more elements chemically bond together.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, and chemical energy.
