Final answer:
Heat can be transferred from one substance to another, but cold cannot. Heat transfer occurs when two objects at different temperatures come into contact with each other, with energy being transferred from the hotter object to the colder object.
Step-by-step explanation:
Heat can be transferred from one substance to another, while cold cannot be transferred as it is not a form of energy. When two objects at different temperatures are brought into contact with each other, the energy is transferred from the hotter object to the colder object until both objects reach the same temperature. This process is known as heat transfer.
Heat transfer is governed by the First Law of Thermodynamics, which states that energy cannot be created or destroyed, only transferred or converted from one form to another. In the case of heat transfer, energy is transferred as heat from one object to another.
For example, when you place a hot metal object in a cooler room, heat is transferred from the metal object to the air in the room, causing the metal object to gradually cool down and the air in the room to warm up.
