On what factors does the rate of heat conduction in a metallic rod in the steady state depend?

= constant) Temperature difference between the hot end and the cold end in steady state is inversely proportional to K, i.e. in case of good conductors temperature of the cold end will be very near to hot end. In ideal conductor where. temperature difference in steady state will be zero.

On what factors rate of flow of heat in conduction depends?

Conduction is the transfer of heat through solids. Factors that affect rate of heat flow include the conductivity of the material, temperature difference across the material, thickness of the material, and area of the material.

What is steady state conditions in heat transfer?

Steady-state heat transfer can be a conduction, convection, or radiation process. Steady-state heat transfer can be described in terms of the temperature as the variable; the temperature of the system remains constant over time in steady-state heat transfer after thermal equilibrium is attained.

What causes conduction of heat through a metal rod?

When one end of a metal rod is heated, the kinetic energy of the molecules at that end increases. Thus the kinetic energy of the neighbouring molecules increases hence their amplitude of vibration increases and during the collision the energy transfers to the next molecule. Thus heat transfer takes place by conduction.

What factor determines the rate in which a material conducts heat?

Factors that affect rate of heat flow include the conductivity of the material, temperature difference across the material, thickness of the material, and area of the material. Different materials have greater or lesser resistance to heat transfer, making them better insulators or better conductors.

What property of matter determines the rate of conduction of heat in a metal?

The rate of heat transfer by conduction is dependent on the temperature difference, the size of the area in contact, the thickness of the material, and the thermal properties of the material(s) in contact.

What factors affect the rate of conduction?

Here are the factors that affect the rate of conduction:

• Temperature difference. The greater the difference in temperature between the two ends of the bar, the greater the rate of thermal energy transfer, so more heat is transferred.
• Cross-sectional area.
• Length (distance heat must travel).
• Time.

What are the two factors affect conduction on the earth’s surface?

Conduction occurs more readily in solids and liquids, where the particles are closer to together, than in gases, where particles are further apart. The rate of energy transfer by conduction is higher when there is a large temperature difference between the substances that are in contact.

What is steady state in conduction?

Steady-state conduction is the form of conduction that happens when the temperature difference(s) driving the conduction are constant, so that (after an equilibration time), the spatial distribution of temperatures (temperature field) in the conducting object does not change any further.

What factors affect conduction?

What causes heat conduction?

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster. As these molecules collide, thermal energy is transferred via conduction to the rest of the pan.
