less dense
Cannonballs are typically made from cast iron or steel. These materials are dense and strong enough to withstand the explosive force when fired from a cannon.
I can't see the specific ball you're dealing with. If it sinks in water, then it's more dense than water. If it floats on water, then it's less dense than water.
Yes, a golf ball typically has a lower mass than a balloon. A golf ball is made of dense materials like rubber and hard plastic, while a balloon is filled with air or helium, which is lighter. The mass of an object is determined by the amount of matter it contains, so the solid material of a golf ball will generally have a higher mass than the gas inside a balloon.
A tennis ball will float in water because it is less dense than water. The air inside the ball helps to keep it buoyant on the surface of the water.
A rubber ball rises up in the water because it is full of a substance (rubber) that is lighter than the same volume of water. A hot air balloon rises up into the cool air because it is full of a substance (hot air) that is lighter than the same volume of cool air. The hot air balloon floats in cool air, just like the rubber ball floats in water.

Freeze it.

No. If the density of the item is less, the mass may be less, even if the object is larger. Cannon ball and a beach ball. Low density beach ball has far less mass than the VERY dense cannon ball, even though the beach ball is larger.
the heated air inside of the balloon has less density than the cold outside air so the hot air is more buoyant (e.g. the bowling ball sinks but the beach ball floats because the density of the beach ball is less than the water)

That depends on what is it made of, however even lead cannon ball would float in mercury, let alone steel one. If you compare densities, you can see that mercury is more dense than lead in room temperature (13530 kg m-3 vs 11 540 kg m-3). One can imagine a cannon ball made of depleted uranium perhaps, which would sink in mercury, being more dense.
A cannon ball.
for at home it is.... 1. drop the red ball in the upper left Conner into the cannon 2.then drop the green ball into the small cannon on the train track 3. drop the bar that is stopping the train track 4.next drop the pink string of the red ball so it will swing then drop the last string so it will fall into the cannon 5. the green ball (not connected to the balloon) should be swinging now just drop it into the box 6. drop the final green ball into the cannon
