Front

According to Boyle's Law, what happens to the pressure of a gas if the volume decreases while temperature is constant?

Back

The pressure will increase.

Front

Front

What describes the movement of two people walking at the same speed but in different directions?

Front

What is a physical property?

Back

A characteristic that can be observed or measured, such as color, state, or hardness.

Front

What is the definition of Boyle's Law?

Back

The principle that states that the pressure of a gas is inversely proportional to its volume at constant temperature.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is a chemical property?

Back

A characteristic that can only be observed during a chemical reaction, such as reactivity or flammability.

Front

What is the definition of a physical change?

Back

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

Front

What is the definition of a chemical change?

Back

A change that results in the formation of new chemical substances.
