Question: If a metal rod is heated at one end, how does the heat travel to the other end?

Options:

Correct Answer: By conduction

Solution:

Heat travels through the metal rod by conduction, as the kinetic energy is transferred from one atom to another.

If a metal rod is heated at one end, how does the heat travel to the other end?

If a metal rod is heated at one end, how does the heat travel to the other end?

Step 1: Heat is applied to one end of the metal rod.
Step 2: The atoms at the heated end start to vibrate faster because they gain energy.
Step 3: These vibrating atoms bump into their neighboring atoms.
Step 4: The energy from the vibrating atoms is transferred to the neighboring atoms, making them vibrate faster too.
Step 5: This process continues along the length of the rod, transferring heat from one atom to the next.
Step 6: Eventually, the heat reaches the other end of the rod.

Conduction – The process by which heat energy is transferred through direct contact between particles in a solid.
