The uppermost layer of the atmosphere is called the exosphere. It feels cold there because, despite high temperatures, the density of air is extremely low, resulting in very few air molecules to transfer heat. Therefore, the heat energy is not felt in the same way as at lower altitudes, where air density is higher and more efficient at conducting heat. This phenomenon leads to a perception of cold in the exosphere despite the presence of high-energy particles.

What is the name of the uppermost layer of the atmosphere and why does it feel so cold there even though the pressure can be very high?

The uppermost layer of the atmosphere is the thermosphere. It feels cold because even though there are few gas molecules present to transfer heat, the few molecules that are present can have very high energies due to high temperatures created by solar radiation. This means that even though the temperature is high, it may not feel hot due to the lack of molecules to transfer that heat.


Is it true that the plumbing vent stacks be straight all the way from lowest to the uppermost level?

No it is not...Based on the size of the vent stack,,they can be horizontal for a short length...Always check with local code though...

Why does the temperature remain constant at the transition temperature even though heating is continued?

At the transition temperature, the heat goes into causing the change in state. Once the change in state is complete, the temperature will change.


Why doesnt your temperature gauge on your 1995 ford mustang work?

What are you talking about? My temperature gauge works fine. Though, if it wasn't I would check the temperature sending unit.


Why are your balls tight even though you are not erect?

Your scrotum adjusts to regulate the temperature of your testes so they are at the perfect temperature for making sperm.


Can you kill sperms by hot towel wraps?

No, though sperm formation benefit from the lower temperature in the testes, increased temperature will not kill them.
