Temperature is really important when we talk about solutions in chemistry.

When the temperature goes up, the molecules start moving around faster. This change affects how much of a substance can dissolve in a liquid and how concentrated that solution becomes.

Let’s break it down:

• Dissolving Solids: Many solids, like sugar, dissolve better in warm water.

  For example, you can dissolve more sugar in hot water than in cold water.

  This can be shown with a simple equation:

  $C_{s} \text{ (s)} + H_{2}O \text{ (l)} \rightarrow C_{s} \text{ (aq)}$

  Here, $C_{s}$ stands for sugar.

• Dissolving Gases: On the other hand, gases don’t dissolve as well in warmer liquids.

  Think about soda. When it gets warm, it goes flat faster because less carbon dioxide ($CO_2$) stays dissolved in it.

In short, temperature affects how concentrated a solution is.

For solids, higher temperatures help them dissolve more.

But for gases, higher temperatures make it harder for them to dissolve.

This idea is really important when we work with solutions in chemistry!
