＜ピーナツをめぐるエネルギーの実験＞
ピーナツに火をつけたら↓↓
Let the peanut heat the small can with the water until the peanut stops burning. Stir the water and measure the temperature of the water and record it in the results table.
ピーナツが燃料fuelとなって水を加熱しています。
In order to light the fuel, you had to put in a small amount of energy.
The fuel however gave out a lot more energy than what was put in.
The difference between the energy you put in and the energy the fuel gave out is how much energy was stored in the fuel.
The OUTPUT ENERGY obtained from a fuel is GREATER THAN the INPUT ENERGY needed to make the fuel burn.
