Q: Is the region where the Space Station is located considered to be at a temperature that is Cold, Warm, Hot, or Extremely Hot?

A: It is Extremely Hot in temperature, but there is almost no heat.

Comments and Sources: The region the International Space Station is in is called the Thermosphere. It is considered part of the atmosphere because the few atoms flying around do hit each other, although IIRC an atom might travel miles before hitting another. At the point where atoms no longer strike each other, it is no longer the atmosphere, again IIRC.

Wikipedia has an article confirming that the temperature can reach over 3500 degrees Fahrenheit, see link. Also see the image showing the space station is in the Thermosphere. The point is that heat and temperature are not the same thing although we tend to think of it that way.

I wanted the image to show here but it is at the top, oh well.
Another illustration: would you be afraid to place your hand in the way of sparks from a flint and steel device? That's around 1370°C. Of course you wouldn't, again there is impressive temperature but almost no heat.

Q: Why is it a bad idea to stand under a tree to shelter from lightning?

A: The height of the tree attracts the lightning, but if it strikes, the lightning will seek the path of least resistance. Wood is a non-conductor, while a human is largely just a column of saltwater. Any lightning striking the tree is then likely to travel to the person.

Q: Zeppelins started attacking Britain in January 1915. The Brits were finally able to shoot one down using an airplane how much later? Was it *Roughly* 1 Month, 6 months, A Year, 18 Months, or 3 years?

A: It was Sept. 1916, way over 18 months and approaching 2 years.

Comments and Source: The Zeppelins were state of the art, having a beginning in the 19th Century, while airplanes were a new development, rushed into production. The first planes were used for scouting, and dropping bombs and firing guns was almost an afterthought. At first for shooting, the pilot would just take a gun with him in the cockpit.

Thus the Brits found themselves having to create defense from scratch including anti-aircraft artillery, searchlights, listening systems, and better aircraft with adequate speed, altitude, and sufficient and proper ammunition. The gas bags were huge and just making leaks from bullets did little. Even the first introduction of incendiary ammo did not work, as a zone of hydrogen and oxygen needed to be created. Finally a combination of regular ammunition with incendiary alternating, and a technique of keeping to the same spot of attack to make a zone, proved effective.
