Yesterday… You learned all about volume…again! What’s the formula for volume? When would you use the formula to find an object’s volume? How could you find the volume of a rock?

All About Volume! Water Displacement Take the next 5 minutes to work with your table group on the Water Displacement Practice Worksheet from yesteday. Water Displacement

All About Volume! 10 g/cm³

All About Volume! 40 g/cm³

All About Volume! 2 g/cm³

Physical Property of Matter Density Physical Property of Matter

Today’s Goals… Know the formula for finding an object’s density. Identify the particle arrangement for objects that are very dense versus those that are less dense. Explain a density column.

Density Formula: DENSITY = mass/volume D =

The closer the molecules are, the denser the object it.

Water has a density of 1.0 g/cm³. Will it sink or float? If something is less dense than the liquid it’s placed in, then the object will float. Water has a density of 1.0 g/cm³. So…if an object has a density of 1.5 g/cm³, then the object will sink.

Density Column:

Density Column:

Let’s Practice… Marble: 50 g; 5 cm³ 10 g/cm³

Let’s Practice… A 10.0 cm³ sample of copper has a mass of 89.6 g. What is the density of copper? 8.96 g/cm³

Let’s Practice… A block of wood 3 cm on each side has a mass of 27 g. What is the density of the block? Hint: Don’t forget to find the volume of the wood first. 1.0 g/cm³

Let’s Practice… An irregularly shaped stone was lowered into a graduated cylinder holding a volume of water equal to 2 ml. The height of the water rose to 7 ml. If the mass of the stone was 25 g, what was its density? 5 g/cm³

Benzene Let’s Practice… Five ml of ethanol has a mass of 5.0 g, and 5.0 ml of benzene has a mass of 45 g. Which liquid is denser? Benzene

At the lab table… Find the density of the three objects: 1) Clothes pin 2) 5 pennies 3) Wood block Record your data in your comp. book. Clean up thoroughly. Pick up the density worksheet.
