Enthalpy of mixing

Okay kiddo, so imagine we have two different things, like water and sugar. When we mix them together, they become one thing. But when we mix things together, sometimes they make heat or take away heat. This is called the enthalpy of mixing.

The enthalpy of mixing is like a thermometer that tells us if the mixture is hotter or colder than the original things we mixed together. So sometimes when we mix things together, like when we mix water and sugar, we make heat, meaning the temperature goes up. But sometimes, like when we mix ice and water, we take away heat, meaning the temperature goes down.

The enthalpy of mixing is important because it helps scientists understand how different substances interact with each other. And if we understand how different things mix together, it can help us make better products or even find new ways to use these substances.
