Matter and Physical and Chemical Properties

Front

What is matter?

Back

Matter is anything that has mass and occupies space.

Front

What are physical properties of matter?

Back

Physical properties are characteristics that can be observed or measured without changing the substance's identity, such as color, density, and melting point.

Front

What are chemical properties of matter?

Back

Chemical properties describe a substance's ability to undergo changes that transform it into different substances, such as reactivity with acids or flammability.

Front

How do you measure mass accurately?

Back

Use a calibrated balance or scale, place the object on it, wait for stabilization, and record the mass.

Front

What is density?

Back

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

Front

What is an example of an intrinsic property?

Back

Density is an intrinsic property because it does not depend on the amount of substance present.

Front

What is an example of an extrinsic property?

Back

Mass is an extrinsic property because it can change depending on the amount of substance.

Front

What is a physical change?

Back

A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition.

Front

What is a chemical change?

Back

A chemical change results in the formation of new chemical substances and involves a change in the chemical composition.

Front

What is an example of a chemical reaction that produces gas?

Back

The reaction between vinegar and baking soda produces carbon dioxide gas.
