Final answer:
A physical change refers to a substance remaining chemically the same, but changing in size, shape, or appearance. During a physical change, the arrangement of particles may change, but the mass, number of atoms, and number of molecules will stay the same option b is correct.
Step-by-step explanation:
A physical change refers to a substance remaining chemically the same, but changing in size, shape, or appearance.
During a physical change, the arrangement of particles may change, but the mass, number of atoms, and number of molecules will stay the same.
For example, when water freezes and turns into ice, it undergoes a physical change. The water molecules rearrange themselves to form a solid, but the chemical composition of water remains the same.
The term that refers to a substance remaining chemically the same but changing in size, shape, or appearance is Physical change. A physical change is a type of change where the form of matter is altered but its identity remains the same. During a physical change, no bonds are broken or formed, meaning that the fundamental structure, including the molecular composition of the substance, does not change. Examples of physical changes include the melting of ice, evaporation of water, and changes in volume or shape.
