The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Purpose of the Gas**: The question asks for the gas used in welding and cutting of metals. Welding and cutting require a gas that can produce a high-temperature flame. 2. **Consider Common Gases Used**: There are several gases used in welding and cutting, such as acetylene, propane, and ethane. However, we need to identify the one that is the hottest burning. 3. **Research the Properties of the Gases**: Among the common fuel gases, ethane is mentioned as a hot burning fuel. However, it is important to note that acetylene is actually known to be one of the hottest burning gases, reaching temperatures up to 3300°C (or about 3600 Kelvin) when burned with oxygen. 4. **Conclusion**: Based on the properties of the gases and their applications, the gas that is most commonly used for welding and cutting due to its high flame temperature is acetylene. 5. **Final Answer**: The gas used in the welding and cutting of metals is acetylene. ---

Argon is used in arc welding because

The simplest method of welding two pieces of metal together is known as pressure welding. The ends of metal are heated to a white heat-for iron, the welding temperature should be about 1300^(@)C -in a flame. At this temperature the metal becomes plastic. The ends are then pressed or hammered together, and the joint is smoothed off. Care must be taken to ensure that the surfaces are thoroughly clean first, for dirt will weaken the weld. Moreover, the heating of iron or steel to a high temperature cause oxidation, and a film of oxide is formed on the heated surfaces. For this reason, a flux is applied to the heated metal. At welding heat, the flux melts, and the oxide particles are dissolved in it together with any other impurities which may be present. The metal surfaces are pressed together, and the flux is squeezed out from the centre of the weld. A number of different types of weld may be used, but for fairly thick bars of metals, a vee-shaped weld should normally be employed. It is rather stronger than the ordinary but weld. The flux is used to
