How come increasing volume doesn’t affect mass?
So I understand mass isn’t weight, mass is the amount of matter in an object

You can increase volume without changing mass by adding more empty space between the particles.

Let’s look at the way ice forms.

When you freeze water in an ice tray, the frozen ice will be bigger and take up more space than the liquid water does. So the *volume* increases while the *amount* of water stays the same (ie mass).

How? Because when water freezes, the water molecules organize themselves into a crystallized shape, and the crystal formation has more space between the molecules than liquid water.
