- Energy and Fuels
- Fuel energy calculated using calorimetry
- Larger the rise in temp more energy been released
- Calorimetry
- Uses a glass or metal container (copper - conducts heat)
- Simple calorimeter
- Polystyrene good thermal insulator - helps minimise energy transfer through sides of container
- Lid reduces energy transfer to surroundings
- Measurements using simple not accurate due to energy losses
- Calculating Energy Released
- Energy transferred (J) Q = mass of water (g) m + SHC of water (4.2) C + Temp changes (oC) triangle T
- Consequences of energy provided by fuel
- Burning fossil fuels release CO2
- Global warming and climate change
- Expensive to slow down the effects
- Developing alternatives costs money
- Crude oil running out and will get more expensive
- Transport food, crude oil used as petrol/diesel so more expensive as used regularly
- Burning fossil fuels release CO2
