Homework Help: science

Posted by liverpool on Saturday, October 21, 2006 at 10:00am.

What happens when a candle is alight (on one side we had to show physical change and on other side the chemical change). The question sheet says 'Explained both changes using the Big Idea of Energy.'

The physical changes are what you can see, and what you can measure. Include heat.

The chemical changes: liquid wax changing to light, smoke, heat?

You need to explain these

Thankyou for your help but what is the Big Ideas of Energy"? Can you explain please?

See my response to Melody near the top of this page.

That's great, thanks.
