Why would heat sensation be weak despite very high temperature in the thermosphere?
Answer and explanation
Correct answer: Heat transfer is low because the number of particles is very small
Temperature measures the average kinetic energy of particles, whereas the sensation of heat also depends on how many particles collide with the body and transfer energy. The thermosphere has extremely high particle energies but very low density, so collisions and conductive heat transfer are limited. Option A is therefore correct. Temperature is not imaginary, pressure is far lower than at sea level, and abundant water vapour is not characteristic of this region.
