Yes and no. For any given power usage, the current in a 220V system is half that of a 110V system. Therefore, cables in a 220V system can be thinner than 110V. Furthermore, a voltage drop of, say, 5V due to the resistance of wires is less significant in a 220V system than 110V. So, there is an economy with wiring. However, touch 220V and there is a good likelyhood that it can prove fatal. Do the same with 110V and it will hurt, but it is less likely to prove fatal. Therefore, 220V systems will generally be of a higher safety standard (read more expensive). For example, US lighting is often wired with single insulated cable. European regulations demand that an additional insulating cover is used on all cables. Other regulations in Europe make more demands on installation methods, all of which push up costs. It is unlikely that a full comparison will show a lot of difference between the two.
The online retailer Amazon currently has an 'Automatic Transformer Adapter 500W 110v/220v 220v/110v' on sale for $38.89. That's 51% lower than the list price of $79.99 and that's before the free shipping!
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.
Charging a Tesla at 110v takes longer than at 220v due to the lower power output. The higher voltage level of 220v allows for faster charging, increasing efficiency and reducing overall charging time for the vehicle.
You cannot directly plug a 110v device into a 220v outlet. This can cause damage to the device or even create a safety hazard. You would need a voltage converter or transformer to safely convert the 220v outlet to the appropriate voltage for the 110v device.
No, a device designed for 110v will not 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.
This is a two part question. Can a 110v outlet be converted into a 220v outlet, yes it can. The other part of the question needs to be discussed.
No
No.
220v and 110v are almost the only voltages used around the world because they are the most efficient.

yes, but you need a transformer to convert it,
