A coffee cup calorimeter will not be used to directly measure the enthalpy of magnesium
combustion because

✓ the coffee cups could melt.

The calorimeter is made of coffee cups instead of
a beaker because coffee cups are

✓ better insulators

than beakers.

You will not measure the enthalpy of the reaction
of

✓ H2 and 02

in the coffee cup calorimeter because this reaction involves gases
Instead, you will use a well-known published
value.
