Den-sity that never sleeps

100

INCLUDE UNITS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Calculate Density:

Mass = 12g

Volume = 4 cm³

12g/4cm³ =             3g/cm³

200

If "Sample B" had a density of 0.7g/cm³ would "Sample B" float or sink in water?

"Sample B" would float

(why? Because 0.7g/cm³ < 1.0g/cm³)

300

Which of these factors affects density? 

TEMPERATURE          or           SURFACE AREA

Temperature

INCLUDE UNITS!!!!!!!!!!!!!!!!!!!!!!!!!

Calculate Volume:

Mass = 24.0g

Density = 6.0g/cm³

Volume = 4.0cm³

500

INCLUDE UNITS!!!!!!!!!!!

Calculate Mass:

Volume = 4.0cm³

Density = 8.0g/cm³

Mass = 32.0g
