What is the definition of 'Volume'?

• The amount of space an object takes up. The formula for a regular shape is L x W x H.

• The weight of an object measured in kilograms.

• The temperature at which an object melts.

• The speed at which an object moves.

What is the definition of 'mass'?

What is the definition of 'density'?

• Density is the amount of mass in a given volume. The formula is D=M÷V.

• Density is the amount of volume in a given mass. The formula is D=V÷M.

• Density is the sum of mass and volume. The formula is D=M+V.

• Density is the difference between mass and volume. The formula is D=M−V.

What is the definition of 'Chemical change'?

• A change in matter that results in new matter that has different properties than the original.

• A change in matter that only affects its shape or size.

• A process where matter is mixed but not changed.

• A change that can be easily reversed by physical means.

What is the definition of 'Physical change'?

• A change in matter that ends with the same type of matter you begin with. This could be a change in size, shape or state of matter.

• A change in matter that creates a completely new substance with different properties.

• A process where energy is absorbed or released but the matter remains unchanged.

• A change that only occurs at the atomic level and cannot be observed.

What is the definition of 'physical property'?

• A characteristic of matter that can be observed or measured without changing the material.

• A process that changes the chemical composition of a substance.

• A property that only appears after a chemical reaction.

• A measurement of the amount of energy in a substance.
