hot to cold is heat transfer
When a cold material interacts with a hot material, heat will transfer from the hot material to the cold material until they reach thermal equilibrium. This will result in the hot material cooling down and the cold material heating up. The rate of heat transfer will depend on the temperature difference between the two materials and their thermal properties.
Hot and cold are used as comparatives. Almost anything can be hot or cold depending on what you compare it to.
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.
Hot water has the energy(heat) to make the change go faster
no. Cold is just the heat in your body leaving so people just think they are cold. Hot is just heat coming in your body.
Yes (with the exception of absolute zero) but the energy in hot and cold is always heat energy. (Cold is defined as the absence of heat)
The heat is released in the environmement by convection.
Penguins die in the heat because when they are born they are already used to the cold if they go to a place that is hot they will die.
temperature can be hot or cold, heat is diff variations of hot.
A thermos keeps hot drinks hot and cold drinks cold by using a vacuum layer between two walls of the container. This vacuum layer prevents heat transfer by conduction, convection, and radiation. The result is that hot drinks stay hot because heat loss is minimized, and cold drinks stay cold because heat gain is minimized.
Heat can usually be considered as the energy of motion of atoms and molecules. Heat can flow spontaneously only from warm to cold. Heat can be made to go in the other direction, but only by doing work. So, the simple answer is: from warm to cold.
