Whats a physical change

Answer 1

A physical change changes the property of a substance without changing the substance completely. In other words, a physical change is reversible.This change that occurs in the physical property/properties of a substance without altering its composition. A physical change:

• Possibly canchange withstate of matter (sublimation, decomposition, evaporation, melting, freezing, and condensation).
• No new material is formed.
• Possibly can dissolve.
• Possibly can occur either by increasing or decreasing the temperature.
• Is reversible.

A physical change is any change not involving a change in the substance's chemical identity.
a physical change is the color shape taste and smell of a substance.
A physical change is where an object changes is size/ shape

Answer 2

A change in a substance that does not change its identity.

EX:

popping a balloon

chopping wood

tearing, crumbling, folding paper

pretty much anything that changes its shape, size, or color without changing its whole identity.

Answer 3

A Physical Change Is When You Mix Somthing Together, But, It Can Always Be Changed Back To It's Original State.(: Made By: Taylor Savage(:
A physical change is a change in the way an object appears, like its form.

whereas a chemical change is a change where the chemicals in a substance change completely into a whole new substance.

Answer 4

Physical Changes

Physical changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (melting, freezing, vaporization, condensation, sublimation) are physical changes. Examples of physical changes include crushing a can, melting an ice cube, and breaking a bottle.

How to Tell Chemical & Physical Changes Apart

A chemical change makes a substance that wasn't there before. There may be clues that a chemical reaction took place, such as light, heat, color change, gas production, odor, or sound. The starting and ending materials of a physical change are the same, even though they may look different.

Answer 5

A physical change is where you can see the change on the outside of something.

For example, take a dog.... if it grows, or its fur gets lighter or darker then it is physically changing.

!!!

Answer 6

Changes that do not result in something new being made.

Answer 7

any of the natural sciences dealing with inanimate matter or with energy, as physics, chemistry, and astronomy.

Answer 8

A physical change alters only the state of matter. It does not change the material's composition. Physical change happens if you cut, grind, bend, break, split, crack or crush a material.

Answer 9

A physical change doesn't affect the chemical formula of a compound.
