The core of Mercury is very hot and not at all cold. The core is made up of iron rich ore which has an almost complete molten liquid global magentic field.
the core is made up of gas,and the surface is rock,craters and dust
yes
It is mostly gas, but it has a solid core.
Mercury's core is made of iron, with a diameter of 3600 km to 3800 km. The silicate outer shell is only 500 to 600 km thick. At least some of the core is molten.

The planet Jupiter is predominantly made up of hydrogen and helium. The core of planet is thought to contain some rock and metallic hydrogen, but Jupiter is mainly made up of gas, hence its classification as a gas giant.
It's mostly made up of gas (including liquid hydrogen). The core is probably rock and ices.
The solar core is made up of a really hot and dense gas (in the plasma state). The temperature of 15 million kelvins (27 million degrees Fahrenheit) keeps the core at a gaseous state.
The Inner core is to be believed to be made up of iron-nickel alloy,while the outer core is made up of iron and nickel
The whole planets made up of gas, and underneath that is a layer of liquid and then a hard rocky core.
Gas giants are primarily made up of hydrogen and helium, with small amounts of other gases such as methane and ammonia. They have no solid surface and their atmosphere becomes increasingly dense towards the core.
The outer core is made up of liquid iron and nickel.
