A silver bullet has a mass of 31.1 g and a density of 10.5 g/mL. What is
the volume of the bullet? ......ANSWER......V=m/d
2.96mL
A metal object has a mass of 8.37 g. When it was placed in a graduated
cylinder containing 20.0 mL of water, the water level rose to 23.1 mL.
What is the density of the metal object? ......ANSWER......d=m/v
2.7g/mL
Fahrenheit to Kelvin ......ANSWER......Need celsius first
*C = *F - 32
-----------
1.8
then

Define specific heat capacity and review the trends in specific heat
capacity values. ......ANSWER......Specific heat capacity of a substance is
the quantity of heat in joules required to change 1g of the substance
by 1*C
A copper medallion with a mass of 72.6 g initially at 21.5 °C was heated
with 684 J of heat. What is the final temperature of the copper
medallion? ......ANSWER......need the SHC of copper = 0.385 J/g*C
then remember the formula:
q=m*C* delta T
Delta T = Tf-Ti
SO
Tf=Delta T + Ti
answer: 46.0*C
What is the specific heat capacity of an unknown metal whose
temperature increased by 10.0 °C. The metal has a mass of 20.4 g and
was heated with 27.0 J of heat? ......ANSWER......q=m*C*delta T
delta T= Tf-Ti
