As you heat any matter you increase the kinetic energy the particles of that matter have. An increase in kinetic energy means that the particles move more and take up more space. This is manifested as an increase in pressure for gases in an enclosed container.
It doesn't change
Depends on the container of the "air particles" and what you mean by "what happens." If it is inside a container that can not expand, then the pressure increases. If it is inside a container that can expand (or is just atmospheric air) then the volume increases. (Pressure * Volume = n * R * change in temperature) On the atomic level, the atoms or molecules (depending on the gas) begin to move more quickly as their kinetic energy increases.
The liquid will expand, it's volume will increase. If it becomes heated enough, it will evaporate (turn into a gas). The more heated it becomes, the more its volume must increase to keep the same pressure.
it goes down
If the fluid was trapt it would be heated by pressure: Like a pressure cooker or the earth's molten core. Otherwise it would just splash about and remain the ambient temperature. The opposite, is like when you use compressed air to clean your computer. While the volume of the container doesn't change the pressure decrease and thus the temperature decreases too. According to Boyle's law pressure and volume fluctuate inversely. But if the volume remains the same, pressure and temperature fluctuate together. Nice and simple: +Positive Pressure = temperature increase+ -Negatve Pressure = temperature decrease- As long as the volume remains the same.
It heats up
It doesn't change
yes because pressure that is confined by a container such as a balloon will increase if the balloon is heated.
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
Given that the container is "rigid" the size of the container holding the gas cannot change. Since the volume of the container remains constant, so too does the volume of the gas. The pressure however will increase.

When air is heated the particles become excited and move and bounce off of surfaces causes pressure on it's container.

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.
its pressure will increase if it is placed in a fixed container, or it will expand if it is free to do so
It doesn't change
the pressure will increase.
The particles will gain kinetic energy and will move faster in the closed container. This will increase the number of collisions they make with the walls of the container, thus increasing the pressure.
