you decided to investigate how much energy it would take to get
solid acetone to gaseous acetone. So assuming you took 125 g of
-100 degree Celsius solid acetone and heated it 56 degree Celsius
gaseous acetone, how many joules of energy would be required to do
this? Acetone has a melting point of -95 degree Celsius and a
boiling point of 56 degrees Celsius. The heat of fusion (melting)
is 98 j/g and the heat of vaporization is 538.9...
