When we play outside on a sunny day or when we turn on the lights in our room, we use energy. But sometimes, even though we use energy, we don't always get the full benefit of it. This is called dissipation.
Think of it like eating your favorite candy. When you eat it, your body gets energy from the sugar in the candy. But if you eat too much candy, your body can't use all the energy and it goes to waste. It's like the energy is dissipating.
In the same way, when we use electrical devices, they use energy to work, but sometimes, some of that energy is wasted and doesn't do the job we want it to. For example, some of the energy used to light up a room might escape as heat and not actually light up the room. This is dissipation.
Dissipation happens in all kinds of things, like when we use our phone or drive a car. Sometimes, energy is lost when it's transformed from one type to another. It's like playing a game of catch and the ball doesn't always make it directly to the other person - sometimes it bounces off something or goes too far. This is called dissipation.
So, dissipation is when energy is used up but doesn't always go towards the thing we want it to go towards. It's like if we were trying to fill up a jar with water, but some of the water spilled outside of the jar and was wasted.
