DERIVED UNITS Obtained by combining different units. Examples: density, speed Density is the amount of mass per unit volume; D = m/v Speed is distance divided by time; S = d/t

DENSITY

DENSITY There are physical characteristics of a substance that help identify the substance. One of these characteristics is density. Density is the amount of matter in a specific volume; mass per unit volume. These 2 cubes have the same VOLUME, but they have different densities. Why?

DENSITY We can calculate the density of a solid, liquid, or gas. Note the difference in units in the formulas of the density of a solid and liquid. The unit for cubic centimeters is cm3 and for milliliters is mL. Since one mL equals one cm3, there is no difference between g/cm3 and g/mL.

DENSITY This image will help you in figuring out how to solve density problems: Simply cover up whichever value you need to calculate and the other two are shown in their proper placement, be it to multiply or to divide.

PRACTICE Which cylinder has the greatest density? What if I had the same amount of each cylinder (1 mL) - which one would have a greater mass?? Vol: 5 mL Mass: 10g Vol: 25 mL Mass: 15g Density = 2g/mL Density = 1.7g/mL

PRACTICE When you work these problems, you need to do the following: Write what you know and where you are going. Write the formula. Plug in the data given and solve. Be sure your answer has the correct unit.

DENSITY PROBLEM A block of aluminum occupies a volume of 15.0mL and weighs 40.5g. What is its density? V = 15.0mL M = 40.5g D = ? D = M/V D = 40.5g/15.0mL = 2.7g/mL

GRO-BEAST LAB Write down all seven pieces of data in your data table. Calculate the density for each set of data. Put the density answers in Calculations column next to Observations and Data table. Then graph the mass and volume data on the backside following the directions. Answer the two conclusion questions Lab is due on THURSDAY.

TO DO Do the five remaining density problems in the notes. Follow the four steps to solving problems. Calculate the density for all seven pieces of Gro-beast data – Graph and answer the two conclusion questions – due THURSDAY. Vocabulary Quiz tomorrow.
