In which of the following does thermal conduction happen fastest? a. liquid b. solid c. gas d. vacuum

The correct answer is Option B.

Explanation:

Thermal conduction is defined as the process in which heat is transferred from hotter object to colder object when they are in contact. Hotter the object, the particles would vibrate with more energy and collide with the nearby particles. This way energy is transferred.

In solids, the particles are closer to each other and the vibration between the particles will be more. Thus, the thermal conduction will be faster.

In liquid and gaseous state, the particles are away from each other and thus, the vibrations will not be fastest.

In vacuum, there are no particles, thus the transfer of energy cannot take place through radiation.

Hence, the correct answer is Option B.

as technology advances, new experiments often expose problems in accepted theories. c
