The short answer is: you can't. The long answer is: just like using a flashlight bulb that has a voltage that is half the voltage of the battery, it will not work. It will take too much current, causing it to burn out and be useless.
Homes in the US and Canada - and other countries which use the same standard electricity supply service - get 240 volts at 60 Hz at the panel. If you don't yet have a a 240 volt socket outlet in the right place for your new appliance then you will need to get one installed.

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.

You don't unless it shows a dual rating on the appliance.
Yes and you will have a spare terminal for future use
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
Off hand no but your explanations are not clear as to who is doing what to whom,,
120v and 240v
Use a step down transformer 240 primary to 120 secondary. You must know what the connected load (amps) is so that you don't overload the transformer. Small transformers are rated in VA.
You can use 120v 10a 125w cable projectors 110-240v power in India.
Power adaptors are readily available that plug into Australia's 240v outlets, converting to 120v. Find them in travel, luggage and electronics stores.

No.
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
Normally you can't use 205V equipment on 120Volts
Off hand no but your explanations are not clear as to who is doing what to whom,,
NO, unless you get a converter that converts 220 to 110.
There are no adptors to plug a 240v plug into a 120v receptacle. 240v requires two hot wores and a neutral and ground. 120v requires one hot wire, a neutral and a ground. If you have something that runs on 240/120 you need the cord and adaptor that came with the equipment as you willl need the wires to mate up accordingly.
