Uh I don't do this event, but I guess I'll kickstart this thing (I don't see any questions..?)

An ideal gas is heated up by 50 degrees Celsius isobarically (meaning at constant pressure). Does its density go up, down, or stay the same? (Bonus: Can you give the ratio of its final density to its initial density?)

Yep!
No because it depends on the starting temperature as well.

Describe processes to measure out the densities of:
a) a metal cylinder
b) a blob of wax
c) some unknown liquid
d) a rubber band ball

I feel like we measured the densities of like half of these in Chemistry today :/
