As the volume is decreased, the same number of molecules of air have a smaller space to move freely in. The number of collisions of molecules of air with the walls of the container per unit time increases. Since pressure is the force exerted over an area, the pressure increases.
if the volume is reduced the gas has less space to move around in so it will exert more pressure on the walls of its container. It is like squashing the same amount of gas into a smaller container, there will be more pressure
true
Yes, but the effect should be minimum. As water cools it becomes more dense, Meaning that there is more mass per volume. As a boat moves through a given volume it must displace some of the water. Since ( F = M * a ) the boat must exert a certain force to move an amount of water. If there is more mass in that certain volume the boat must exert more force, thereby slowing the boat.
Assuming constant amount of gas and temperature, pressure will increase as volume decreases. Conversely, pressure will decrease as volume increases. If you squeeze on a filled balloon, the volume decreases. The pressure of the air on each square inch of the balloon increases, which causes it to eventually pop if the pressure gets too high. Assuming constant amount of gas, a temperature change will already change the volume of the gas. As temperature rises, the gas expands, causing more pressure to be exerted on the balloon. Assuming constant temperature, adding more gas also increases the volume and thus increases the pressure.
pressure. simple answer is pressure. what happens is that as the gas gets hotter they move move and want more volume, if you don't allow them that volume the pressure goes up. when you get a gas colder, the opposite happens and makes the pressure go down.
Lying on an air mattress
The pressure is reduced to one third of the original pressure. The pressure will stay the same you are only changing the volume
Pressure exerted
It doesn't unless it is constrained in a constant volume container. When in a container, as the air is heated its molecules vibrate more and take up more volume - as the volume of the container is fixed then Charles's law applies and the pressure goes up.
It will fill any container you evaporate it into, and still exert pressure on the inside of the container in its relentless quest for more volume. That's just what gases do.
Salt water is denser, and therefore will exert more pressure (for two columns of the same height).
on your toes
Total pressure is the same in either case, but on your toes, you exert more pounds per square inch, on fewer square inches.
Assuming your cylinder is fixed and has something like a piston allowing for potential movement, the volume will remain the same. The gas will become less densed, as with pressure its more dense.

Water is more dense than air is.
Sorry - it exerts more pressure than a flt heel.
The gymnast exerts more pressure by doing the split because she has a bigger surface.
This is the reduction of volume to one-third.
