Well, similar appliances generally use similiar power (measured in watts), but also generally, plugging in a 110 volt appliance into a 220V plug will probably destroy it.
... and watts equals volts times amps. An appliance designed to run on 110V might draw 3 amps therefore will burn 330 watts. A similar appliance designed for 220V would probably draw only about 1.5 amps, yet also obviously burns 330 watts.

power = voltage x current.........so, a 220 volt appliance would use half as much current to do the same work as a 110 volt appliance....Ohms Law....P=E x I where E is voltage and I is current in amps. Power is in watts.

Yes. It uses exactly the same wattage; the current is halved when the voltage is doubled. (Assuming the appliance is properly wired for the other voltage, of course.)

No, since the resistance of the appliance will remain constant, it will draw double the current when connected to 220V as compared to 110V and may burn out.

those 2 numbers are voltage. Every time you double the voltage you cut the amps in half. and vice versa.

Yes.
