What is density?

Back

Density is the mass of a substance divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

What is a model in science?

Back

A model in science is a representation of an object or system that helps explain and predict its behavior.

Front

What is the process of melting?

Back

Melting is the process where a solid turns into a liquid when heat is applied.

Front
