It depends, the ice cube can have the same amount of water in it but if its flatter or if it has a greater surface area it will melt faster than one with less surface area.
Because it changes from a solid shape (ice cube) to a liquid shape (Water)
nothing
A melting ice cube is a physical change, because the ice cube is only changing size, shape, volume and state of matter.It's not a chemical change, because it's not changing into a different kind of matter with different properties.
Due to their varying melting points (ice 32 and sugar 366°)
you can put sawdust on the ice cube
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
how do i keep and ice cube from melting with out foam for 8 hours
One way to keep an ice cube from melting away is if you keep it in ice water.
yes it does. the more surface tension the cube has, the faster it will melt b/c the more surface tension it has, the more its exposed to its environment or something like that. but the shape of the ice cube does affect the melting time.the answer above is true. the more surface area the shape of the ice cube has makes it melt faster. take a cube ice cube for instance. it has 6 sides so it would have more surface area then per say a sphere, which has no flat surface.
Melting of ice is at 0 oC.
Usually a cube. Some ice makers shape their ice into crescent shapes, however.
Because the melting temperature of the ice is 32°F and the melting temperature of the salt is 1,474°F.
