Ice Definition and 963 Threads

for my science fair project, i need to know the properties of an ice cube (physical and chemical). I am trying to see if the madd/weight of an ice cube effects its "flicking" distance. don't ask. :) please help!

Ok, so you've got a glass of water with some ice (the ice is floating). After the ice melts, does the water's surface level a) rise? b) lower? c) stay the same? (and why?)

after anuclear war as most know a nuclear winter will ensue. many people don't know however most dot know that this will cause a snowball Earth with the entire planets surface covered in snow and until another million or so years the atmospheres gasses won't trap enough heat to melt the snow but...

stuck in explaining this problem A glass of water contains a large ice cube the glass can hold no morw water the ice is floating in the water what will happen to the water level when the ice melts?

The question is "8 grams of water at 100 degrees C are poured into a cavity in a very large block of ice initially at 0 degrees C. How many g of ice melt before thermal equilibrium is attained round off to the nearest whole number?" As I understnd it I need to: (heat to change ice to...

An ice skater doing a toe spin with outstretched arms has an angular velocity of 4 rad/s. She then tucks in her arms, decreasing her moment of inertia by 7.5% a. What is the resulting angular velocity? b. By what factor does the skater's kinetic energy change? For a, I use IW = I'W' >>...

I am fairly new to chemistry, so this might seem like a stupid question, but I am still interested nonetheless. A burbon on the rocks exists because ice is less dense than water, but how can this be the case when the molecules in a solid are closer together?

Hey all, I got this e-mail forwarded to me, and I wondered if any of you had seen it yet. I'm scepticle as to the claims within, because it sounds like an urban legend. What do all of you think? This was sent to me buy the man in the Bat Cave. [name deleted out of courtesy] We thought is...

Dry ice forms at -109.6oF. The record low natural temperature measured on Earth (Antarctica) was approximately -129oF. Does the solidification of carbon dioxide mediate temperature there, either by heat of sublimation or reduction of greenhouse effect? Would long-term global climate be...

"Unusual warm spots on Mars might represent "ice towers" similar to those seen in Antarctica, say researchers. They could even harbour life, Nick Hoffman of Melbourne University told a conference on Thursday." http://www.newscientist.com/news/news.jsp?id=ns99993986

Are we in the middle on an ice age now? I do not think that we are but my friend does.
