What is necessary for heat conduction?

What is necessary for heat conduction?

(i) The two objects should be in direct contact with each other. (ii) The temperature of the two objects should be different. Heat will flow from a hotter object to a cooler object.

Does conduction require a fluid?

Heat conduction is a phenomenon that enables heat to be transferred within an object. Heat conduction can occur in solids, not only in fluids such as liquids, and gases.

Does conduction require a medium?

Conduction requires a medium to transfer heat by contact of particles. Radiation transfers heat through electromagnetic waves, and can transfer heat with or without a medium.

What are the two necessary conditions required for conduction?

(i) The two objects should be in direct contact with each other. (ii) The temperature of the two objects should be different. Heat will flow only from a hotter object to a cooler object.

How does conduction occur in fluids?

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer to together, than in gases, where particles are further apart.

How does conduction take place in fluids?

Conduction as we know happens when the ‘atoms or molecules’ of two objects are close enough or in contact. But in liquids too this phenomenon works, the molecules of liquid move and collide with one other thus producing heat energy which then moves from the end that is so hot to the end that is cooler.

Why is medium necessary for conduction?

medium is required for conduction of heat because heat passes from one molecule to another molecule of the medium..the molecule starts to vibrate because of the pressure of heat and the vibration is passed from one molecule 2 another.

What are the conditions necessary for conduction to occur Class 7?

Answer: For conduction of heat from one object to other, it must satisfy two conditions. Firstly, the objects should be in contact with each other. Secondly, they should have different temperature.

What are the two conditions necessary?

Two conditions must be met in order for work to be done on an object. The first is that the object moves. The second is that a force must act on the object in the direction the objectmoves.

How is conduction used?

If you are cold and someone holds you to warm you, the heat is being conducted from their body to yours. If you leave a metal spoon propped up in a pot, it will become hot from the boiling water inside the pot. Chocolate candy in your hand will eventually melt as heat is conducted from your hand to the chocolate.
