The expression "close the window, because the cold is coming inside the room"

• Is true, the transference of heat happens from cold materials to hot materials

• Is false, the transference of heat happens from cold materials to hot materials

• Is true, the transference of heat happens from hot materials to cold materials

• Is false, the transference of heat happens from hot materials to cold materials

The thermal equilibrium happens when...

• Two materials with different thermal energy transmit energy one to another so they reach the same level of energy and temperature.

• Two materials with the same thermal energy transmit energy one to another so they reach the same level of energy and temperature.

• Two materials with different kynetic energy transmit energy one to another so they reach the same level of energy and temperature.

• Two materials with different potential energy transmit energy one to another so they reach the same level of energy and temperature.

Heat can be transmitted via...
