Liquid expands by Diffusion. Its simple Middle school science. To be more precise, its osmosis. As water moves from place to place there becomes more water "Molecules" Its impossible though for liquid (water to expand). It just takes the form of what it is in. There is no way you can gain unless you add more to it physically. I'm a Middle Schooler. It's simple Science!

When a liquid is heated, its molecules gain energy and move faster, causing the liquid to expand. As the temperature increases, the average distance between molecules increases, leading to an increase in volume. This expansion is the reason why liquids (and most materials) increase in volume when heated.

What three things determine how much liquid you can load?

The amount the liquid will expand in transit. The weight of the liquid. Legal weight limits.


Why not measure amounts of liquid when hot?

Heat = expansion. The water molecules expand when heated. The container will expand, and then the measurment will be off?


What is the effect of heat on liquids?
