a ice cube melts when it heats up
Water :)
Salt melts ice cubes.
It melts faster alone because the others are not cooling it off.
It melts slowly.
salt melts ice because it wants it to die
Yes the volume of ice changes when the ice melts. In fact the volume of ice goes on increasing up to 0 degree Celsius and when the ice melts completely the volume of ice decreases on the contrary. Yes because when ice freezes, it expands and when it melts, it gets smaller.
Table Salt.
Melts
Sugar has very little effect on melting point - it is too high molecular weight. That might answer your question, which does not make sense as written. Thus, it melts faster with sugar, because other ice cubes slow melting.
Heterogeneous. You can see the parts of the mixture with the naked eye. The parts of the mixture are: the tea and the ice cubes. Once the ice melts, it will be a homogenous mixture.
A bunch of ice cubes would melt faster than a block of ice. This is because the ice cubes have a greater surface area exposed to warmer temperatures causing accelerated heat absorption.
No. Water expands when it freezes so when it melts, it will take up a smaller volume.
