Class Notes Topic: ________________________ Questions/Main Ideas: Name ________________________________________ Class ________________________________________ Period ________________________________________ Date _____________________________________ Notes: Intro to Density 1. What is mass effected by? 2. Will changing the volume change the density? How tightly packed the particles are in a substance. vs. A block of iron has very tightly packed compared to aluminum. NO. Density is a RATIO between mass and volume….the particles remain packed the same way no matter what the size of the sample.
3. What are three ways to find volume? 1)Use a G.C. 2)bxh 3)displacement 4. Will changing the volume change the mass? Yes. You will have more particles so mass will increase. BUT the density is the same. vs.
The length is 3 cm the width is 4 cm and the height is 5 cm. The length is 4 dm, the width is 6 dm and height is 9 dm. The volume is? The length is 10 m, the width is 4 meters the height is 7 meters. The volume is?
