Will the earths core ever cool down?

Since the earth is constantly rotating wont that cause friction with the magma, creating more heat? So will the core ever reach a cool state? Can liquid even create heat through friction?

Yes, someday the core will cool down and solidify. Laws of thermodynamics wouldn't let the core be hot forever. Eventually the earth will bleed off even the energy of the core until is a dark lifeless solid rock.... Unless the sun expands and swallows earth first.
