What does it mean when there is a physical change?
A
Matter has changed size
B
Matter has changed shape
C
Matter has changed form
D
All of the above
Explanation: 

Detailed explanation-1: -Physical change is a process in which the substance experiences change in its physical properties like shape, size, colour, volume, appearance, state (i.e. solid, liquid, gas), etc., that, without making any change in their molecular composition.

Detailed explanation-2: -Physical change is a type of change where the physical properties of matter change. A change of state of matter, change in colour, odour, solubility, etc. all are examples of physical change. During a physical change, neither the composition nor the chemical nature of matter is changed.

Detailed explanation-3: -The changes in which only physical properties of substances are changed and no new substance is formed is called a physical change. It is a reversible change. Example: Boiling and freezing of water.

Detailed explanation-4: -Some common examples of physical changes are: melting, freezing, condensing, breaking, crushing, cutting, and bending.

Detailed explanation-5: -Some types of physical changes include: Changes of state (changes from a solid to a liquid or a gas and vice versa). Separation of a mixture. Physical deformation (cutting, denting, stretching).
