Water is the only material to my knowledge you can see in all three states, solid = ice; liquid = water; vapor = steam (crap I could have made that an entry in this forum).

Ice floats because it has air in it, vapor rises because it is lighter than air, and hot water rises because it is less dense than cold water.

When you set up an electric water heater you set the lower thermostat at a higher temperature than the upper thermostat that way you get a constant circulation of the water to inhibit calcium build up.

 

Hell, I didn't even know they had two thermostats.

 

He means a blue reflector in the road indicates that there is a fire hydrant adjacent to it (at least in Cali). It has nothing to do water flow.

 

A blue reflector on the street indicates a hydrant. http://www.slate.com/blogs/the_eye/...f_history_of_reflective_pavement_markers.html

The flow rate of the hydrant is indicated by the color of the top, and caps, of the hydrant. http://www.firehydrant.org/info/hycolor.html

Both of these conform to NFPA standards.

 

Ahhh my mistake, thanks.

 

Even metals like iron can boil (3134 K) and gases like Hydrogen can be a solid (14 K). As far as liquids that we normally see at room temperature ammonia (usually mixed with something) boils and freezes. I actually can't think of anything that can't be a solid, liquid or vapor. It's also possible to have all three states at once if the material is at its triple point.

Ice floats because it is less dense than liquid water. At about 4 C (when water is at its most dense) a crystalline structure starts to form, which takes up more space.

 

Ya, there are some obvious ones, and some that aren't. I wasn't interested in getting into a debate though.

 

I debunked the blinking while sneezing...

 

I seem to remember a Mythbusters episode on that.

 

Just saw this question on a game show....

When dealing with motor oil, what does the W stand for in 10W-40?
A) Weight
B) Winter
C) Water
D) Wear

 

B. Winter

 

Weebles wobble but they don't fall down.

Young guys on this forum won't know what I'm talking about. Now get off my lawn!

 

You must be one of the young ones

 

Same as us

 

I'm 42 too

 

I'm 43. How can you not know what they are? GTS.

 

Does GTS mean google that shit?

 

Yes sir. You know your milennial acronyms

 

I remember weeble wobblers

 

Only 80's commercial I remember is...
"OB, it's the way you should be. Keep it simple, and set yourself free..."

 

You dropped some knowledge without meaning to drop some, never heard of "GTS" before haha.

 

Funny thing is I learned that from a 60 year old LOL
