all metal can melt
That depends on the metal: mercury is already liquid at room temperature, gallium will melt in your hand, many alloys will melt in hot water, but other metals do have to be heated to thousands of degrees before they melt.
If gold gets hot enough, it will melt. What type of change is this?
It will melt.
No. Lava is generally not hot enough to melt steel.
This super hot iron cannot melt because of all the pressure.

Although metal can get very hot a microwave does not produce enough energy to heat most metals to their melting points.
You need to define "metal"- since different metals have VERY different melting points. Mercury is melted at room temp. Gallium can melt in boiling water. Lead and tin are mixed as solder, and melt at fairly low temps. Gold and silver melt at moderate low temps. Aluminum is higher. Steels and hi temperature tungsten alloys will glow white hot before melting. So- which metal did you have in mind

Depends on the metal, but for steel it is hot enough to melt the steel- and steel melts at 2600-2800 degrees F.

It will melt.
Not usually. If the flame is very hot, the metal may melt.
Yes, it will, if you get it hot enough.
No, some burn or decompose before they get hot enough to melt.
No. Lava is generally not hot enough to melt steel.
