What is heat conduction?
Q: What is heat conduction?
A: Heat conduction is the transfer of heat between two objects of different temperatures when they come into contact with each other.
Q: Can heat conduction occur between objects of the same temperature?
A: No, heat conduction only occurs between objects that have different temperatures.
Q: What is an example of heat conduction?
A: An example of heat conduction is warming your hands by touching a hot-water bottle. When the colder hands come into contact with the hotter water bottle, heat flows from the hotter object to the colder one.
Q: What are some materials with different thermal conductivity?
A: Cookware can be made of materials with different thermal conductivity, as well as insulated containers for hot or cold items.
Q: Are there other ways besides conduction to transfer heat?
A: Yes, heat can also be transferred through radiation and convection.
Q: Do all heat transfer processes happen separately?
A: No, usually more than one of these heat transfer processes (conduction, radiation, and convection) happen at the same time.
Q: Can heat transfer occur in a vacuum?
A: Yes, heat transfer through radiation can occur in a vacuum. This is how the Sun's heat reaches the Earth.
