A pot of water is heated over a fire, and then frozen peas are added to the hot water. What happens to the energy in this situat
ion? The energy gained by the peas is lost by the water.
The peas lose energy as they are heated in the water.
Energy is transferred from the peas to the water and the pot.
The water receives energy both from the fire and from the frozen peas.
Energy is transferred from the fire to the pot, then to the water, and then to the peas.
When a pot of water is heated then molecules of water will gain kinetic energy. Whereas frozen peas have potential energy initially but when they are added into the hot water then energy will transfer from water to the peas.
Therefore, molecules of peas will also gain kinetic energy.
So, we can conclude that energy is transferred from the fire to the pot, then to the water, and then to the peas.
By observing chemical reactions, we are able to understand and explain how the natural world works. Chemical reactions turn food into fuel for your body, make fireworks explode, cause food to change when it is cooked, make soap remove grime, and much more.
