Here's why:
* Conduction: Heat transfer through direct contact between objects. The hotter object's molecules vibrate faster, transferring energy to the colder object's molecules, causing them to vibrate faster as well. Metals are excellent conductors because their free electrons can easily transfer energy.
* Convection: Heat transfer through the movement of fluids (liquids or gases). This is not relevant in this case as we're dealing with a solid metal.
* Radiation: Heat transfer through electromagnetic waves. While metals can radiate heat, it's not the primary method by which they absorb heat from another object in direct contact.
