why is cold air heavier than warm air? I understand the particles are moving more slowly/have less energy but why does that make them heavier? Let's say you have two balloons, one filled with 10 'hot' particles and one with 10 'cold', won't they weigh exactly the same?

Because being less motive as a result of having less energy is just fundamentally the way the universe works.

Why do sweet things taste sweet, instead of non-sweet?

yeah, but the hot one will be expanded larger and have a lower density
if you take a fixed volume of air instead of a fixed number of particles a volume of cold air will have more particles in it than the same volume of hot air

Ya but the balloon with 10 hot particles will be more expanded and thus displace more air and have more bouyancy
