Energy and Fuels
Fuels provide ENERGY - but there are consequences
Burning fuels
Release co2
Global Warming
Climate Change
Crude Oil is running out
Fuels like diesel and petrol will become more expensive
Big economic effect
Everything transported by lorry, train or plane gets more expensive
Fuel energy is calculated using calorimetry
Different fuels produce different amounts of energy
Measure energy release =burn the fuel and use the flame to heat up water
Method
1) Put 50g of water in the copper can and record its temperature
2) Weigh the spirit burner and lid
3) Put the spirit burner underneath the can, and light the wick. Heat water, stiring constantly, until the temp reaches about 50'C
4) Put out the flame using the burner lid, and measure the final temperature of the water
Re-weight the spirit burner and lid
So we're measuring:
Mass of spirit burner & lid. Before & After
Temp of water. Before & After
ENERGY TRANS=MASS OF WATER X SPECIFIC HEAT CAPACITY OF WATER X TEMP CHANGE
Calorimetry uses a GLASS or METAL CONTAINER (usually copper)
