Question

If crushed ice is pressed and then the pressure is released, a lump of ice
is formed. Justify it.​

Answer 1

Justification for rushed ice is pressed and then the pressure is released, a lump of ice  is formed:

• It is true that if crushed ice is pressed and then the pressure is released, a lump of ice is formed because the melting point gets lowered that form water.

• When pressure is released water freezes due to a decrease in pressure and inclusion in the freezing point making the cubes stick together.  

• The freezer experiences defrost cycle which radiates heat.

• Many times, the ice in the freezer naturally absorb the heat which causes the ice to melt during the defrost and they bring out ice clumps.

1. When crushed ice is pressed, its melting point is lowered and some ice melts to form water.

2. When pressure is released, the melting point becomes normal and the water freezes to form ice forming a lump.
