Is heat energy transferred from a warmer object to a cooler object?

Answer 1

No, heat ALWAYS travels from hot to cold. It is not actual heat moving, it is energy. The more energy something has, the warmer it feels. For example, when you touch a metal railing on a winter day, it feels cold. That is because your hand has more energy than the rail. The energy from your hand is traveling into the railing to equalize the energy (moving towards equilibrium. The loss of energy in your hand is what gives you the "cold" feeling. Heat/energy NEVER moves from cold to hot.

Answer 2

Yes, always. According to the second law of thermodynamics, heat of its self can never pass from one body to a hotter body. This means that a cold thing can never use what little heat it has to warm up a hotter thing without outside help.

Answer 3

Heat is caused by the vibration of molecules in matter. This is a form of kinetic energy. When a warm object is in contact with a cooler object, the molecular vibration (kinetic energy) flows from the warm object to the cooler object until they reach both reach thermal equilibrium. (That is, until they are the same temperature.)

Answer 4

• yes heat does always move from one warm substance to a cooler one.

Answer 5

Yes, this happens spontaneously. It actually flows both ways, but the hotter object loses energy faster, so the system will try to reach equilibrium.

Answer 6

yes through radiation

Answer 7

yes
