Convection, Conduction and Radiation

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) where warmer, less dense areas rise and cooler, denser areas sink, creating a circular motion.

What is the role of gloves in keeping hands warm?

Back

Gloves help keep your hands warm because they are insulators, preventing heat loss.

Front

Which material is the best conductor of heat?

Back

Steel is the best conductor of heat among the given options.
