Chapter 16:Chemistry Way, Way Below Zero

1. Why is it significant that tin can form alpha and beta shapes of its crystals?
This causes their shape to change which causes "Tin Leprosy".

2. Why was it so hard for scientists to make a compound from argon?
It  is hard for them because argon won't grasp onto anything. It also requires very frigid temperatures.

3. What does maser stand for? Laser?

Microwave Amplification By Stimulated Emission of Radiation- MASER Light Amplification By Stimulated Emission of Radiation-LASER

4. Besides making strong lasers, neodymium can help make the worlds strongest LASERS.

5. Why does Bose Einstein Condensate require such an extremely cold temperature? 

Although I didn't read this in the book, I saw online that the temperature of the condensate is used so that the atoms can somehow not be individual atoms but merge and combine.
