What does Mass mean?

• The weight of an object measured in pounds.

• The amount of matter in an object, usually measured in grams or kilograms.

• The volume of an object measured in liters.

• The density of an object calculated by its mass and volume.

What is Plasma?

• A state of matter similar to gas with charged particles, found in stars and lightning.

• A type of liquid that conducts electricity.

• A solid material that can be easily molded.

• A gas that has no mass.

What is a Gas?

• A gas is a state of matter that has no definite shape and no definite volume.

• A gas is a state of matter that has a fixed shape and volume.

• A gas is a state of matter that can be easily compressed and has a definite volume.

• A group of two or more atoms bonded together.

• A type of chemical reaction between elements.

• A substance that cannot exist independently.

What is Density?

• Density is the measurement of how much mass of a substance is contained in a given volume, calculated as mass divided by volume.

• Density is the total weight of an object regardless of its size.

• Density refers to the temperature at which a substance changes state.

• Density is the measure of how much space an object occupies.

What is the difference between a Chemical Change and a Physical Change?

• A chemical change results in the formation of new substances, while a physical change does not change the chemical composition of the substance.

• A physical change results in the formation of new substances, while a chemical change does not change the physical appearance of the substance.

• Both chemical and physical changes result in the formation of new substances.

• A chemical change only affects the physical properties of a substance, while a physical change affects its chemical properties.

What is an Atom?

• An atom is the smallest unit of matter that retains the properties of an element.

• An atom is a type of molecule that can exist independently.

• An atom is a particle that cannot be divided into smaller parts.

• An atom is a form of energy that can be converted into matter.
