A very cold ice cube may appear to smoke, but actually what you are seeing is water vapor. The air around the ice cube is cooled by the cold ice cube, and when it cools, water vapor in the air condenses into fog.
Its not smoke - IF you see it, its water vapor in the air condensing.
The metal tray has both a higher specific heat (ability to gain or hold heat) and a higher conductivity (ability to transfer heat). So while the ice cream will increase in temperature where you touch it (and hence only absorb a small amount of body heat), the tray can absorb more heat, and transfer it to all of the metal and ice in the tray. (This is also why you can lick a wooden pole in the winter, but not a metal one!)
The hot water tray because some of the water evaporates, and it takes less time to freeze.
Depends on the tray and the size of the cubes. Can't really answer without more specifics. soniczev
ice doesn't smoke. what you are refering to is what happens when something really cold meets with something warmer then it's self.
Yes, this is a physical change.
What you see is not smoke; it is mist. When you pull the ice cube tray out, a bit of air from the freezer comes with it. This air chills the room temperature air to below freezing, causing the moisture in it to form microscopic ice crystals.
It's vapor, not smoke. To be maintained as a solid, water must be kept at a freezing temperature. When the ice tray is taken out, it gets immediately exposed to the much warmer ambient air. The heat from the ambient air transfers to the ice, and causes the top layer to undergo a rapid change of state - the most immediate change of state is a vapor form.
The water at the top is more exposed to cold air than the water at the bottom of the ice tray.
The question was not how many cubes are in a tray but how many cups of ice were in a tray. An average ice tray equals about two cups of ice
When water freezes it expands and the only way it has to go in an ice tray is up.
The answer is D. The metal ice-cube tray has a higher conductivity.
There realy isn't a name for it, I would just call them "the ice tray wholes" or "ice sockets".
Tray
Melt the block, fill an ice cube tray with the water then freeze the ice cube tray.
Ice cubes crumble when you empty the tray because they have stuck to the surface. This causes the ice crystals to shatter when they are forcefully removed.
well.... if u have a ice cube tray u can pour some juice into the ice cube tray and freeze it. It will work best with oj.
if the tray is metal. i think it could be tried.
