Question

The mode of heat transfer that does not require a medium is________(a) Conduction (b)Convection (c) Radiation (d)Expansion

Answer 1

Answer:

(c) Radiation, is the right answer

Answer 2

Answer:

The mode of heat transfer that does not require a medium is radiation i.e.option(c).

Explanation:

Let's analyze the options one by one.

(a) Conduction -Conduction is the method of heat transfer in solids when heat transfer occurs without the movement of medium particles.

(b)Convection-Convection is the method of heat transfer in fluids where heat transfer occurs as a result of the movement of medium particles.

(c) Radiation-Radiation is a type of heat transmission in which heat is transported from one location to another without changing the particles of the medium.

(d)Expansion-volume growth brought on by a rise in temperature.

Hence, the mode of heat transfer that does not require a medium is radiation i.e.option(c).
