Aim

Measure the temperature of 50 ml of water as it boils and find how long it takes to boil.

Equipment
measuring cylinder,beaker,tri-pod and gauze mat,bunsen burner, lighter, water and fire

Method

  1. Measure exactly 50 ml of water in the 100 ml measuring cylinder.
  2. Put this water in the 250 ml beaker, and set that up on top of the tri-pod and gauze mat.
  3. Prepare the bunsen burner to be lit, and have someone ready to measure the temperature and someone keeping a track of time.
  4. Have a table prepared for results.
  5. Light the bunsen burner (I will supply a lighter), and change to the blue flame then put the bunsen under your beaker.
  6. Measure the water temperature every 30 seconds from 0 to 5 minutes.
  7. Turn off the bunsen burner and leave everything to cool off for a few mins.
  8. Pack up your equipment.
