How does a Cruise ship float if it is so heavy? Yet a penny will sink?
What is its total density is less dense than the water
300
Will preforming a physical change on an object change its density? Explain Ex: cutting a peice of paper with scissors
What is NO. The density will remain the same.
300
Will preforming a chemical change on an object change the density of the object? Explain. Ex: burning a peice of paper with a candle
What is Yes. You have created a new substance therefore you have a new desity.
