Bubble point

Imagine you are blowing soap bubbles with a wand and a jar of bubble solution. You dip the wand in the solution and then blow the wand to make a bubble. As you do this, you add more and more air to the bubble. The bubble gets bigger and bigger as you add air.

Now, imagine that the bubble solution represents a liquid, and the air represents a gas that is dissolved in the liquid. The amount of gas that is able to dissolve in the liquid depends on a few things, like the temperature and pressure.

The bubble point is the point at which the gas is no longer able to stay dissolved in the liquid, and starts to come out of the liquid and form bubbles. This happens when the pressure or temperature changes, and the amount of gas that can be dissolved in the liquid decreases.

So, just like when you blow bubbles and eventually the bubble gets so big that it pops, the same thing happens with a liquid and gas mixture when the pressure or temperature changes and the gas comes out of solution. This is called the bubble point.
