because thermocol is lighter than water
Hypotonic Solution
It will slow - sound moves faster in water than in air.
You use the thermacol to cast the part. Then you use the resulting mold to reproduce the item.
Because the water molecules moves faster when heated and therefore, the volume expands.
Water moves out of the cell in hypertonic solution.
Because the heat supplied to thermocol is absorbed by the water inside thermocol and this continues till the temperature reach the boiling point of water. Once the temperature reaches to boiling point of water then the temperature of water inside the thermocol is same as the temperature on the outer side of thermocol facing the heat and then only the thermocol glass will start burning.

hypertonic solution!
It is in a Hypotonic Solution.
Warm water of course.

It will slow - sound moves faster in water than in air.
Osmosis
Water moves along concentration gradient. So solution is hypotonic.
in water yes its density is less than density of water
The gradient of a stream affects the speed of the water as it moves downstream. The steeper the gradient, the faster the water moves.
