So what do you think

[Kansas Kid]

1.  Is it possible to take an icecube tray, full of water, and place it in the desert on a clear day when the air temperature is higher then 32F and have it turn to ice.

 

2.  Is it possible to knock a building over with approximately .5psi of pressure placed on then entire surface of an exterior wall?

 

So what do you guys think, possible or not?  And if so, explain why.  I will explain both in a day or so....

[pacodiablo]

yup, i guess

[Jpshostr]

1)  Yes, make sure the ice tray is inside an operating freezer that you take to the desert with you.

 

2)  Yes, since the direction the wall is falling isn't said, make sure the inside of the wall has a done of pressure put on it.  

 

Can't tell me I'm wrong here Kyle!

Sounds like good answers to me ?!?!?!?!

1) hmm I supose if the air temp was 32.1*f and there was a nice breaze the evaporation would get it to freeze (may evaporate first)

 

2) tower 1,000' tall X 100' wide = 100,000 ft2 x144= 14,400,000 in2 X 5= 72,000,000 pounds /2000= 36,000 tons

 

 

36,000 tons force, a tower may be able to hold the weight in the tower but I do not know if it could hold it as a side load

maybe the twin tower absorbed more energy than that on impact (767 weighs more than that + inirtia) they did not fall until the fire weakened them I thin they were wider than 100'

Looks like we got answer for question number two.  I don't think there is a building out there right now that could hold a 36000 ton side load.

 

Still looking for the answer on number 1, and no JP yours doesn't count.  Notice how the sky has to be clear....

You could place the ice tray in the desert on a clear day, and then it could freeze later that night, when the temp drops below freezing.

Questions about question #1 what kind of desert are you talking about?  A Sahara type desert, a Death Valley type of desert, a Painted Desert type of desert, a Phoenix type desert?  Tom I spent 11 years just east of Phoenix and even in the winter time when the day time temps didn't make it much above 80 it never got down below about 43 degrees F.  It even snowed one day and the air temp was about 44 degrees.

Alright, I'll give "riddle" #1 a shot.......

 

 

Yes, if it is a 33F air temp, then, it has to be up like 1000s of feet up in the air.

 

How does that sound?

 

 

And go ahead, ask me "General, Where the hell did you get that Idea from?"  

[Stepside Z]

I am not sure about the answer to question 1 but I have a question, If a tree falls down in the woods and their is nobody there to hear it does it make any noise?

[General Lee 01]

So, are you going to tell me I'm right or what?

[Kansas Kid]

Well, its kind of confusing how #1 can actually happen.  And no it doesn't have to be place in a freezer, the air temperature doesn't have to be 33F with a strong breeze, or any of that kind of stuff.

 

In the desert, on a clear day, all the heat from the water will be lost through radiation.  Normally ice freezes through convection, and in that case the air temperature does have to be below 32F.  But on a clear day in the desert, the ice will lose all the heat it has by radiation and will freeze.  And it won't work on a cloudy day, because then none of the heat can be lost through radiation.  So did that confuse everybody?  LOL
