What is the difference between a physical change and a chemical change?

Back

A physical change alters the form or appearance of a substance without changing its composition, while a chemical change results in the formation of new substances.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent, such as water.

Front

What are the three states of matter?

Back

The three states of matter are solid, liquid, and gas. Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither a definite shape nor volume.

Front

What is an example of a gas?

Back

An example of a gas is air, which is a mixture of gases including oxygen and nitrogen.

Front

How can you determine the properties of a powder?

Back

You can determine the properties of a powder by observing its color, texture, solubility in water, and other tests such as smell or taste.

Front

What does it mean when a new substance is formed?

Back

A new substance is formed when the properties of the original substances change, indicating a chemical reaction has occurred.

Front

What is the importance of observing changes in properties?

Back

Observing changes in properties helps scientists understand how substances interact and whether a chemical change has taken place.
