Why does the Fahrenheit scale use 32 degrees as a freezing point?

When liquid boils what TYPE of gases are in the bubbles?

Would this be perpetual motion:
1) You make hydrogen from water using energy.
2) you let the H₂ rise through a pipe capturing all its energy.
3) you burn the H₂ in a fuel cell at its highest height.
4) Then you let the water from the fuel cell run down a pipe capturing all of its energy.
5) Now all the energy you captured from the H₂ rising, the fuel cell burning,and the water falling is used to make more H₂.

What is the temperature at which Fahrenheit and Celsius thermometer readings are equal?

Expansion and Contraction : Why does heat and cold make things expand and contract ? Also why do some metals expand more than others?

Can you compress a liquid (water)?

Which freezes faster, hot water or cold water?

Do you know where to find information on the temperature at the tip of a lit cigarette, both during drawing on it and when it is not being drawn on?
