A student took out a cup of frozen water from the freezer. At what temperature would the water begin changing from a solid to a liquid?
A
0
B
50
C
100
D
150
Explanation: 

Detailed explanation-1: -Fresh water transitions between the solid and liquid states at 32°F (0°C) at sea level.

Detailed explanation-2: -The water kept in the freezer cools down and after a point its state changes from liquid to solid (ice). The temperature at which this happens, is called the freezing point of water. This process of conversion of a substance from liquid to solid at freezing point is called freezing. Q.

Detailed explanation-3: -The freezing point of water, when liquid turns to solid, is 0 degrees Celsius. At this point, the internal energy of the water is reduced, the atoms become closely packed, and ice is formed. Internal energy is used to describe the energy associated with the random motion of molecules and the bonds between them.
