Question #1: D
Question #2: B
These are the correct answers hopefully. I knew the second one, but the first one I had to look up and do a wee bit of research

Answer:
Absolute Zero
Explanation:
It is based on molecular motion, with the temperature of 0K, also known as absolute zero, being the point where all molecular motion ceases. The freezing point of water on the Kelvin scale is 273.15K, while the boiling point is 373.15K
It wouldn't be 0 degrees C or 0 degrees F because the temp of the molecular motion stop in Celsius is -273.15 degrees and in Fahrenheit it would be -459.67 degrees.
I hope this helps :)
