This question does not make sense. Hard 'solids' can turn to liquid with enough heat, be it ice or steel.
Slower
Ice melts slower
Yes it does
Water because soda has many chemicals that make it melt slower.
foam insulation
The objects fly slower during the winter.
melt them.
They melt objects and later hardens into igneous rock
you suck
It has a thicker consistency. :)
No, rough objects and smooth objects fall at the same rate in a vacuum due to gravity acting on them equally. In the presence of air resistance, rough objects may experience a slightly slower acceleration due to increased drag.
Yes, putting different objects in ice cubes can affect the rate at which they melt. Objects that conduct heat well, like metal or salt, can speed up the melting process by transferring heat to the ice faster. Objects that insulate, like plastic or paper, can slow down the melting process by preventing heat transfer.
