Plasma

Question 11

What is the temperature for Absolute Zero?

Answer 11

-273.15 c
0 kelvin
-473.5 Farenheit

Question 12

What is the Heating Curve for water?

Answer 12

A representation of how water changes from one state to another, depending on the thermal energy.
- The temperature does not change in the phase changes.
- Heat/thermal energy is added or realized.

Question 13

Bose Einstein Condensate characteristic

Answer 13

• It is an artificial state of matter, it has not been founded on Earth, rather created by humans.
• Very low energy = almost absolute zero.
• Low energy: molecules cannot perform their wave-like-motion.
• Atoms gases connected to a very low temperature - no energy.
• No temperature: almost 0 kinetic energy
  As a result… atoms clump together SUPER BIG ATOM!
