Heat Transfer | MCQs

Explanation

• Copper is an excellent conductor of heat, having a high thermal conductivity (386 W/mK).
• This means it can efficiently transfer heat energy with minimal resistance.
• Metals (e.g., iron, copper, silver, mercury, aluminum) are good conductors of heat.

Explanation

In solids, heat transfer occurs primarily through conduction, where vibrations and collisions of particles (atoms or molecules) transfer energy from one point to another.

Explanation

• Conduction is the transfer of internal energy (heat) through direct contact between particles or molecules.
• Including collisions and movements of electrons within a substance.
• This process occurs in solids.

Explanation

• A thermal conductor is a material that allows heat energy to flow through it easily.
• Such as metals like copper, aluminum, and iron.

Explanation

• As temperature increases, the heat energy of a substance also increases.
• This is because temperature is a measure of the average kinetic energy of the particles in a substance, and as temperature increases, the particles gain kinetic energy and therefore heat energy.
