If heat can flow between them, then heat flows from the hot one to the cold one.

The temperature of the hot object falls, and the temperature of the cold object

rises. What drives the transfer of heat is the difference in temperature, so as soon

as both objects are at the same temperature, the process stops, and no more heat

is transferred.

Do cold things have heat?

No, cold things do not have heat. Heat is a form of energy that is transferred from hot objects to cold objects. Cold objects have less heat energy compared to hot objects.


What could be the temperature at cold objects compared to hot objects?

Cold objects generally have lower temperatures compared to hot objects. The temperature of a cold object is typically below room temperature (20-25 degrees Celsius), while the temperature of a hot object is usually above room temperature. The temperature difference between cold and hot objects can vary depending on the specific temperature of each object.


What happens to air when it gets extremely cold?

The particles in the air come closer together and don't move as much.


Does heat travel from cold objects to hot objects?

No, heat naturally flows from hot objects to cold objects. This is based on the second law of thermodynamics, which states that heat always moves in the direction that increases the entropy of a system.


If one object is hot and another one cold?

If the objects are brought into contact with one another, it's very likely that heat will flow from the hot object into the cold one, and that their respective temperatures will tend asymptotically toward the same value.


Why do objects get smaller when they are outside (in the cold)?

Objects may appear smaller when exposed to cold temperatures due to contraction of their molecules. When the temperature decreases, the molecules within the object lose kinetic energy, causing them to move closer together. This leads to a decrease in the overall size of the object.


What happens if a cold egg is brought into hot water?

Basically, the egg gets warmer as the water gets cooler until both meet at the same temperature.


How does thermal energy transfer from hot objects to cold objects?

Thermal energy transfers from hot objects to cold objects through a process called conduction. This occurs when the particles in the hot object collide with the particles in the cold object, transferring energy and causing the cold object to heat up.


Does cold objects have heat energy?

Yes, even cold objects have heat energy. Heat energy is a form of energy that is present in all objects, with colder objects having less heat energy compared to hotter objects. This energy is related to the temperature of an object, with colder objects having lower temperatures and less heat energy.


Which form of energy moves spontaneously from hot objects to cold objects?

Heat energy moves spontaneously from hot objects to cold objects through a process called heat transfer. This transfer occurs until both objects reach thermal equilibrium, where they have the same temperature.


What could be the temperature of hot objects compared to cold objects?

Hot objects have a higher temperature than cold objects. Temperature is a measure of the average kinetic energy of the particles in a substance, so hot objects have faster-moving particles than cold objects.
