In the thermosphere temperature rises rapidly with height, but why would heat feel weak there?
Answer and explanation
Correct answer: Air particles are extremely sparse
The correct answer is A because temperature measures the average kinetic energy of individual particles, whereas the feeling of heat depends greatly on how many particles transfer energy to the skin. In the thermosphere, particles may move very fast, giving a high measured temperature, but the air is extremely thin. Therefore, very little energy is transferred by collisions. Options B, C, and D are incorrect because ozone is not the main reason, pressure is far below sea-level pressure, and water vapour is not abundant there.
