Is it a physical change when water in an ice cube tray freezes?
Yes, freezing of water in an ice cube tray is a physical change. It involves a change in state from liquid to solid without altering the chemical composition of water molecules.
How many milliliters is in an ice cube?
Size is irrelevant. An ice cube can be any size, so long as it is frozen from a liquid state in its container (remember, liquids fill their containers). However, a standard-size ice cube from a tray is 1.2 cubic inches (roughly--the cubes usually slope slightly, changing their volume). Also, their size depends on how much water you place in the tray before freezing.
Why do ice cube trays have plus and minus signs on each end?
The plus and minus signs on ice cube trays are for you to indicate the direction you need to twist or pull to release the ice cubes from the tray more easily. The signs help you know which way to apply pressure to prevent the tray from breaking when separating the cubes.
Metal ice-cube tray and a plastic tub of ice cream are sitting in the freezer Why does the ice-cube tray feel colder to touch than the tub of ice cream?
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!)
What makes ice cubes stick in the tray so they won't come out?
Two things: Water expands as it freezes which applies force to the inside of the ice cube tray, holding it in place. Most ice trays are plastic and semi-porus. Some of the water molecules find their way into these small pores and when they freeze, joining to the rest of the cube, it acts kind of like molecular velcro.
A metal ice-cube tray and a plastic tub of ice cream are sitting in the freezer. Why does the ice-cube tray feel colder to touch than the tub of ice cream?
The answer is D. The metal ice-cube tray has a higher conductivity.

Why ice disappears from your ice cube tray what may be possible reason?
