Heat Transfer Practice

Front

What is conduction in the context of heat transfer?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids where heat is transferred through direct contact between particles.

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal spoon warms up after being placed in a hot bowl of soup.

Front

What is radiation in the context of heat transfer?

Back

Radiation is the transfer of energy through electromagnetic waves, which can occur in a vacuum and does not require a medium.

How does radiation differ from conduction and convection?

Back

Radiation transfers heat through electromagnetic waves, while conduction transfers heat through direct contact and convection transfers heat through the movement of fluids.

Front

What is convection in heat transfer?

Back

Convection is the transfer of heat by the physical movement of a fluid (liquid or gas), where warmer areas of a fluid rise and cooler areas sink.

What is an example of convection?

Back

An example of convection is the heating of water in a pot on a stove, where hot water rises to the top and cooler water sinks.

What is the role of heat lamps in keeping baby chickens warm?

Back

Heat lamps transfer heat to the baby chickens primarily through radiation, providing warmth without direct contact.

What is the formula for calculating heat transfer by conduction?

Back

The formula for heat transfer by conduction is Q = k * A * (T1 - T2) / d, where Q is the heat transfer, k is the thermal conductivity, A is the area, T1 and T2 are the temperatures, and d is the thickness.

What factors affect the rate of heat transfer by conduction?

Back

The rate of heat transfer by conduction is affected by the material's thermal conductivity, the temperature difference, the surface area in contact, and the thickness of the material.

What is thermal conductivity?

Back

Thermal conductivity is a measure of a material's ability to conduct heat, with higher values indicating better heat conduction.
