Examples of coffee-cup calorimeter in the following topics:
-
- A simple example of a constant-pressure calorimeter is a coffee-cup calorimeter, which is constructed from two nested Styrofoam cups and a lid with two holes, which allows for the insertion of a thermometer and a stirring rod.
- As such, the outer cup is assumed to be a perfect insulator.
- A student heats a 5.0 g sample of an unknown metal to a temperature of 207 $^\circ$C, and then drops the sample into a coffee-cup calorimeter containing 36.0 g of water at 25.0 $^\circ$C.
- The walls of the coffee-cup calorimeter are assumed to be perfectly adiabatic, so we can assume that all of the heat from the metal was transferred to the water:
- A styrofoam cup with an inserted thermometer can be used as a calorimeter, in order to measure the change in enthalpy/heat of reaction at constant pressure.
