Experiment 16: Coffee And Milk

Aim

The aim of this experiment is to find out if a steaming cup of coffee stays warm longer when leaving it untouched, or pouring cold milk into it

Theory

Physics informs us that large quantities of liquid take longer to cool than smaller quantities. Since there are more molecules in a larger quantity of liquid it may take longer to heat, but once the molecules are heated they take longer to cool down than a smaller quantity of water. Therefore I expect the beaker where the milk has been added straight away to have a higher temperature

Apparatus

  • 2 measuring cylinders
  • Bunsen burner
  • 2 thermometers
  • Stirring rods
  • A larger beaker
  • Tripod
  • Coffee powder
  • Cold milk
  • Water

Procedure

  1. First of all the coffee has to be made. Pour some water in the large beaker and heat it using the Bunsen burner. Once the water is boiling sprinkle the coffee powder into the beaker and stir it until the coffee is made.
  2. Now pour equal amounts
