What are the conditions that are necessary for conduction of heat?
Conditions necessary for conduction of heat
Conduction of heat is the transfer of heat energy from one point to another within a material or between two materials in contact. For conduction to occur, certain conditions must be met. These conditions are:
- Temperature difference: There must be a temperature difference between the two points or materials for heat to flow.
- Medium: Conduction can only occur in solids, liquids, and gases. It cannot occur in a vacuum.
- Contact: For heat to flow from one object to another, the objects must be in contact with each other.
- Area: The area of contact between the two objects determines the amount of heat transferred.
- Time: The amount of time the objects are in contact determines the amount of heat transferred.
Explanation of conditions necessary for conduction of heat
- Temperature difference: Heat always flows from a hotter object to a colder object. This means that there must be a temperature difference between the two objects for heat to flow.
- Medium: Conduction can only occur in materials that have particles that can vibrate and collide with each other. Solids, liquids, and gases have these types of particles, but a vacuum does not.
- Contact: For heat to flow from one object to another, the two objects must be in contact with each other. This allows the particles in the hotter object to transfer energy to the particles in the colder object.
- Area: The greater the area of contact between the two objects, the more heat will be transferred. This is because there are more particles in contact with each other, allowing for more energy transfer.
- Time: The longer the two objects are in contact, the more heat will be transferred. This is because there is more time for energy transfer to occur between the particles of the two objects.
In conclusion, for conduction of heat to occur, there must be a temperature difference between two objects, they must be in contact with each other, and the objects must be in a medium that allows for energy transfer to occur. The area of contact and the time the objects are in contact also play a role in determining the amount of heat transferred.

What are the conditions that are necessary for conduction of heat?
The following are the conditions that are necessary for conduction of heat... 1. heat always flow or move from the hotter object to the collet one. 2. Once that occurs heat transfer process stops. 3. Heat transfer can occur in three ways: conduction, convection, radiation.
