Question

Quizplus · Accepted Answer

At an altitude of 300 km, there is almost no air present. So, the air density is very low which means that there is no medium for heat transfer to take place. As a result, even when the temperature is high, the astronaut would feel cold as there is no heat transfer taking place from his body to the surrounding environment.
