Answer: Option (1) is the correct answer.
Step-by-step explanation:
The internal energy of an object obtained by the kinetic energy of its molecules is known as thermal energy.
Since thermal energy is basically due to the kinetic energy of molecules, that is, rapid movement of molecules and this kinetic energy is released to the surroundings in the form of heat.
Therefore, we can conclude that thermal energy produced is not generally usable to do work because the thermal energy dissipates too quickly and is not concentrated enough to be used.
