Question

Is Boiling An Egg Conduction Or Convection?

Answer 1

Conduction: The process of transmission of energy from one particle to another is called conduction, but here each particle of the medium remains in its position.

• In physics or chemistry, conduction is primarily understood as the transfer of heat energy through a material.
• Conduction can occur in solids, liquids, and gases.

Convection: Convection is the process of heat transfer by the bulk movement of molecules within liquids such as gases and liquids.

• The initial heat transfer between the object and the fluid occurs through conduction, but the bulk heat transfer is due to the motion of the fluid.
• When a liquid is heated from below, thermal expansion occurs due to which the lower layers of the liquid become less dense due to overheating.
• Buoyancy causes the less dense and hotter part of the liquid to rise and the cooler and denser liquid takes its place.
• This process is repeated until the liquid becomes uniformly heated. In this way, heat is transferred by convection.

The boiling process of eggs is the process of conduction.

• The heat is transferred from the boiling water to the egg shell and then to the egg liquid.
• The process of boiling an egg involves the transfer of heat from one particle to another.
• The transfer of heat from one particle to another is the process of conduction.
