Physical & Chemical Properties

What does the term "Physical Property" refer to?

• A property of matter that describes a substance's ability to participate in a chemical reaction

• A characteristic of a substance that does not involve a chemical change

• The ability of a material to conduct heat from one side to the other

• The force exerted by magnets when they attract or repel each other

What is meant by "Chemical Property"?

• A characteristic of a substance that does not involve a chemical change

• The ability of a substance to cause harmful health effects.

• A property of matter that describes a substance's ability to participate in a chemical reaction

• The ability of a material to be stretched, pulled, or drawn into a thin wire or thread without breaking.

What does "Density" measure?

• The temperature at which a liquid changes into a gas

• The ability of a material to conduct heat from one side to the other

• How much space an object or substance takes up (volume) in relation to the amount of matter in that object or substance (mass), it is a ratio.

What is "Boiling Point"?

• The point at which materials change from a solid to a liquid.

• The temperature at which a liquid changes into a gas

• A measure of how quickly a specific material is capable of catching fire and burning
