 Density is a measure of how much matter (objects that take up space) is compacted in an area.  What is the formula? Density = mass OR mass ÷ volume.

Which do you think would have the greater mass and greater volume? Why? 1 kg of rock 1 kg of feathers.

DENSITY

MASS & VOLUME All matter has mass & volume Mass is the amount of matter that an object contains Volume is the amount of space something occupies

Density Density is the measurement of how much matter is packed into a given volume. The mass of atoms, their size, and how they are arranged determines the density of the substance.

WHICH STATE OF MATTER WOULD BE THE MOST DENSE? Density Of Matter WHICH STATE OF MATTER WOULD BE THE MOST DENSE?

NO MATTER HOW BIG OR HOW SMALL When a piece of matter is broken off or compressed together, the ratio of mass and volume stays the same. The density of the matter remains the same no matter how big or how small the sample.

Density & Size A piece of cake is as dense as the entire cake Water is the same density no matter how much water is in the sample

Calculating for Density Calculate for density if the mass and volume is known Mass M Density = Volume = V Unit of measure • solids = g/m3 or g/cm3 • liquids = g/l or g/ml

Density is LOVE!!!

Use this triangle to help you! Density Triangle Use this triangle to help you! If you need to find the MASS, cover up the M Mass = Density x Volume If you need to find the VOLUME, cover up the V Volume = Mass ÷ Density This also works for finding DENSITY! Cover up the D Density = Mass ÷ Volume

Let’s try a few problems… Calculate the density of an object that has a mass of 24 grams and a volume of 127mL. 0.189 g/mL Calculate the density of an object that has a mass of 54 kg and a volume of 32 Liters. 1.688 kg/L Calculate the density of an object that has a mass of 10 g and a volume of 5 mL. 2 g/mL

Sink or Float Water has a density of 1g/ml Any solid with a density greater than 1g/cm3 will sink less than 1g/cm3 will float.

More dense than water Less dense than water Equal density to water
