"Power" is not expressed in volts, but rather in watts (Volts times Amperes), for instance. So you cannot say whether 110v or 220v is more Power-ful unless you also know how much current (Amperes) is flowing in the electrical circuit.
No, a device designed for 110v will not work on 220v without a voltage converter.
No, a device designed for 110v cannot work on 220v without a voltage converter.
To convert 110v to 220v using a step-up transformer, connect the 110v input to the primary winding and the 220v output to the secondary winding of the transformer. The transformer will increase the voltage while maintaining the power output.

220v and 110v are almost the only voltages used around the world because they are the most efficient.
Depends. Some smaller stuff can usually run on both, in which case it will be printed on them. If it isn't, you can't run a 220v item on 110v.
The fact that it's supposed to. Voltage is stated as the difference between the two wires carrying electricity to the load. When they bring power to the house from the utility, you get two wires carrying 110v but they're 180 degrees out of phase. Imagine one carries positive 110v and the other carries negative 110v. If you hook one of these wires plus a neutral (zero volts) to the load, you get 110v--110v over 0v. If you hook both of them to the load, you get positive 110v over negative 110v, or 220v. So...red to white is 110v, black to white is 110v, red to black is 220v.
No.It'll overload and fail just about immediately.It's possible - but not recommended - to run two 110 v heaters in series from a 220v circuit.
yes, but you need a transformer to convert it,
All three, on 110V a split receptacle, on 220V a baseboard heater, on 440V a construction heater or similar resistive load.
