and measure the final temperature of the water. Weight the spirit burner and lid again.
- Uses glass or metal container
- Different fuels release different amounts of energy
- Q = mc^T. Energy transferred(j) = mass of water(g) x specific heat
capacity of water (4.2) x temp change(c)
- Burning fossil fuels releases C)2. This causes global
