Dynamic equilibrium

Have you ever played with a seesaw in a park? When both ends have the same weight, it stays still and you can sit on it without falling either way.

Similarly, dynamic equilibrium happens in our body, where different forces balance out to keep things stable.

For example, our body temperature stays around 98.6°F (37°C) even when we are outside in extremely hot or cold weather. This happens because our body generates heat to warm itself up and sweats or shivers to cool down according to the environment temperature. These opposite forces balance out the body temperature and keep it steady, which is dynamic equilibrium.

Another example could be a chemical reaction, where the rate of forward reaction equals the rate of reverse reaction, and the concentration of reactants and products remains the same. It's like a seesaw of reactions trying to reach a balance, and when they do, it's dynamic equilibrium.

So, dynamic equilibrium is when different forces balance out, and everything stays constant and stable. It's like a seesaw that doesn't tip either way, and that's because everything is in harmony.
