- P1.2 Energy Transfers and Efficiency
- Energy cannot be created or destroyed.
- During energy transfer only a portion of the energy is useful.
- Wasted energy is transferred to the surrounding
- Wasted energy spreads out so becomes less useful.
- Wasted energy is transferred to the surroundings, which becomes warmer.
- Efficency= useful/total (x100)
