physical changes are anything that can be undone, eg

  • crumpling paper
  • chopping wood
  • building with legos
  • freezing water
  • boiling water
  • dissolving salt water

chemical reactions can't be undone, eg

  • baking cookies
  • those hot packs for ski trips
  • putting an alka seltzer in water

What is the differnce between physical and chemical change?

Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.

Is water evaporating and condensation are examples of a chemical change?

no. Those are physical changes.


Is water condensing a chemical change?

No, it is a Physical Change. Physical Changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (condensation, melting, freezing, vaporization, sublimation) are physical changes. Other examples of physical changes include crushing a can, melting ice, and breaking a bottle. Chemical changes take place on the molecular level. A Chemical Change produces a new substance. Some examples of chemical changes include combustion (burning) and rusting of a metal.


Which occurs more often on earth physical changes or chemical changes?

Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.

Differences between physical and chemical changes?

Well, darling, a physical change involves a change in appearance, like cutting a piece of paper, while a chemical change involves a change in composition, like burning that paper to ash. So, in simpler terms, physical changes are like a makeover, just changing the looks, while chemical changes are like a complete transformation, changing what's on the inside. Just remember, physical changes are skin-deep, but chemical changes go straight to the core.
