  • 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)
