Answer 1

CO2 is able to be trapped in liquid. That’s why sodas are fizzy. There is a small space in every soda container that contains CO2 or nitrogen. When you agitate the container, it causes the CO2 to escape the liquid. This is why a shaken can of soda feels tighter. That gas trapped in the liquid is trying to escape to the small gas pocket but there isn’t enough room.
