1.8 g/ml is the density

If a 96.5 g piece of aluminum has a density of 2.7 g/cm3, what is its volume?

35.7 is the volume of the piece of the aluminum

physical change

A change in a substance that does not involve a change in the identity of the substance

chemical change

A change in matter that produces one or more new substances

weight

A measure of the force of gravity on an object

What is matter?

Anything that has mass and takes up space

What remains the same no matter how much of a substance you have?

Density

What is true about all matter?

It has mass and takes up space

how do you find the volume of a solid?

If two substances have the same volume, but the first one has greater mass than the second one, which one will have the greater density? Why?

The one that has more mass has more density because the more mass it has the more density it has.

Difference between mass and weight

Weight is affected by gravity, but mass isn't
