Give me 5 examples of physical change & chemical change?

If I remember correctly chemical change- bubbles, smell, color, temperature, light emitted, taste… I think there are more.

Physical… Seems kind of obvious.

Try reading your book instead of asking Fluther to help you with your homework.

Look in the back of the book, you might have to open it first though.

Just a thought.

After 30 seconds of googling I found this

Physical Changes
Change of state (such as from solid to liquid or from gas to liquid)
Specific examples of state change include water freezing, alcohol evaporating and dry ice (solid carbon dioxide) subliming
Absorption of water into a towel
Crumpling a piece of paper
Pulling copper into a thin wire – a change of shape, but not a change of composition
Cutting a material such as wood
Ripping a piece of tin foil
Breaking glass
Deflating a basketball
Mixing different solids (such as solid sulfur and iron filings)
Inflating a volleyball

Chemical Changes

Burning a log of wood.
Mixing an acid with a base, producing water and a salt.
Photosynthesis – a process in which carbon dioxide and water are changed into sugars by plants.
Cracking heavy hydrocarbons to create lighter hydrocarbons (part of the process of refining oil).
cooking examples:popcorn cake & eggs
oxidation examples:rust or tarnishing
The following can indicate that a chemical change took place, although this evidence is not conclusive:
Change of color (for example, silver to reddish-brown when iron rusts).
Change in temperature or energy, such as the production (exothermic) or loss (endothermic) of heat.
Change of form (for example, burning paper).
Light, heat, or sound is given off.
Formation of gases, often appearing as bubbles.
Formation of precipitate (insoluble particles).
The decomposition of organic matter (for example, rotting food).

Bad Joey! No! Don’t do that anymore.
I smack you with a rolled up newspaper on the nose.

I’m sorry, I’m sorry, but stupid, obvious questions just need answering

boo. :)

my bad
Oh, and welcome to Fluther :D

I did my homework already. I don’t want to do yours, too.

I have a science exam on wednesday :(

Physical Change: Michael Jackson
Chemical Change: Ozzy Ozbourne

It’s not ‘da’ answer, but it is an answer

Ph. cut paper, break rock, break wood, wear on coin, wind erosion. Ch. digestion, rust, cell growth, pain, mixing epoxies.

Damn it, Steve!

Might want to take a peek at your English book, while you’re at it.
