== == == == Assuming this inquiry is a request for information rather than related to a practical application, here is the answer: It will work but you probably won't like the results. You are not going to get the amount of light you should or probably want. I would hook up the proper size light, or the proper juice for the light. A 240 Volt rated tungsten filament lamp will glow dimly if 120 Volts are applied.
The resistance of the filament will limit the current to a level below that which will raise the filament temperature to high enough a level to glow fully bright.
The same thing would hold true if one applied 60 Volts to a 120 Volt lamp.
If you are contemplating installing a 240 Volt European fixture in the U.S. [the idea that may have motivated the question], there are manufacturers who make a 120 Volt lamp with a base for the 240 Volt fixture sockets. Yes, a 240 Volt incandescent lamp will work in a 120 Volt application, but you won't get half the light. You'll get a lot less than half, even though the applied voltage is half the rated voltage. There are hardly any sensible reasons to run a 240 Volt lamp in a 120 Volt application. <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Visually most people will not see a lighting difference. The 240 bulb will be minimally brighter, but will last longer which is why it is more preferable to use.

yes
Power is measured in Watts, power (Watts) = E (volts) x I (current - amps) current is determined by the internal resistance (R) of the lightbulb, the lower the resistance the more current will flow. 120v x 0.5a = 60W 120V x 0.83a = 100W the 100W lightbulb will draw more current We also have Ohm's law: E(volts) = I (amps) x R (ohms) Household voltage stays the same at 120v we have for a 100w lamp: 120v = I x R R = 120v/0.83 amps R = 144.6 ohms for a 60w lamp: 120v = I x R R = 120v/0.5 amps R = 240 ohms The higher watt lamp has lower resistance.
The average air compressor uses only about 120v. Which is the average house socket. Thus using about 400 Watts of power.
The number of CFL bulbs that can be used on a single pole dimmer depends on the wattage of the bulbs and the maximum load capacity of the dimmer. Each dimmer has a specified maximum load capacity, usually measured in watts, which indicates the total wattage it can handle. To determine how many CFL bulbs can be used, divide the dimmer's maximum load capacity by the wattage of the CFL bulbs being used. Make sure not to exceed the dimmer's maximum load capacity to avoid potential overheating and damage.

You don't, at least, not legally.
yes

Yes. The bulb will be slightly dimmer, but will last much longer. Most 145V bulbs are intended to be used in 120V exit signs. The reason for the higher voltage rating on the bulb is because it will last a long, long time when used at 120V.
No, the cord ends have different configurations to prevent this sort of thing from happening.
Household is 120/240 volts at 60Hz. The average wall socket is 120v 60Hz.
