Kinetic Theory and Density

 The amount of matter in the object  How much an object weighs.

 Is a measure of the pull of gravity on an object.

Density Notes. What is density? How much mass is in a volume How much matter is in a given space How compact particles are in a space Which is more dense?

Density. Take a look at the two boxes below. Each box has the same volume. If each ball has the same mass, which box would weigh more? Why?

Matter Review Physical Science

Anything with mass and volume Not chemically combined Two or more elements chemically combined Atoms Build these Atoms are the building blocks of all matter! Same Throughout *Solutions* Different Throughout * Easily separated*

What makes each state of matter different is how tightly the particles are held and how much energy there is.

We use properties, a trait that matter possess, to help us classify various types of matter.

Chemical Changes: Did it turn into something new? Physical Changes: Did it just change appearance yet is still made of the same thing?

Phase Changes are Physical Changes

Temperature: A measure of the kinetic energy of molecules F = 1.8 C + 32 K= C =273 5/9 (F-32) 60 F= _____ C 34 C= ______F 28 C= ______K

A rock has a mass of 50 g and a volume of 5 mL, what is its density? Density= Mass/Volume Volume= l x w x h A rock has a mass of 50 g and a volume of 5 mL, what is its density? An object has a mass of 20 g and its density is 10 g/mL, what is its volume?

The object in the diagram to the left has a mass of 100 g The object in the diagram to the left has a mass of 100 g. What is the object’s density? If the object to the left has a density of 2.08 g/cm3, what must its mass be?
