characterize properties as intensive,
extensive, or chemical
List additional properties during the chapter
Intensive
Extensive
Chemical
__________ granular texture
__________ length
__________ state of matter
__________ density
__________ reacts with acid
calculate density
Dental aprons are required for patients receiving X-rays.
These aprons contain a standard 0.30 mm thickness. An
adult apron is 58.5 cm x 66.0 cm. Calculate the mass of lead
in an apron if the density of lead is 11.3 g

REMEMBER: convert mm to cm, watch significant figures!
calculate quantities related to specific heat
What is the amount of heat required to
increase the temperature of 100. grams of
aluminum by 10.0 0C? The Cp is 0.21J/g 0C.
If 20.0 grams of gold is heated to 142.0˚C and
then added to 30.0 grams of water at 20.0˚C
the equilibrium temperature is 22.43˚C.
Calculate the specific heat of gold. The
specific heat of water is 4.18J/g˚C.
