Calorimeter Experiment
Question | Answer |
---|---|
What is a Calorimeter? | A device used to measure the amount of heat involved in a physical or chemical process. |
4.2 Joules? | 4.2 Joules raises the temperature of 1ml of water by a degree |
Energy released | temp.change x volume of water (ml) x 4.2 |
Energy content | energy released/change in mass |
Biggest problem in calorimetry | Heat loss to surrounding air due to lack of insulation |
How can this problem be fixed? | Use a good insulating material like aluminium foil to keep heat concentrated in one place |
Stirrer (Bomb Calorimeter) | Distributes food evenly around the water for an accurate measurement of temperature rise |
