The correct answer is a. Heat always travels from warmer objects to colder ones.Heat transfer occurs when there is a temperature difference between two objects or systems. Heat will naturally flow from the warmer object to the colder object until thermal equilibrium is reached, meaning both objects or systems have the same temperature.Option b is incorrect because heat does not travel from colder objects to warmer ones. This is the opposite of the natural direction of heat transfer.Option c is incorrect because heat transfer is not solely dependent on elevation. While it is true that warmer air tends to rise and cooler air tends to sink, this is not the only factor that determines the direction of heat transfer.Option d is incorrect because heat transfer is not solely dependent on pressure. While it is true that heat can transfer from areas of higher pressure to areas of lower pressure, this is not the only factor that determines the direction of heat transfer.In summary, heat always travels from warmer objects to colder ones until thermal equilibrium is reached.
