What happens when a, certain quantity of pure ice is completely changed to water at 0oC?
latent heat is absorbed, the mass remains constant, and the volume decreases
latent heat is given out, the mass remains constant and the volume decreases
latent heat is given out, the mass increases and the volume remains constant
latent heat is absorbed, the mass decreases and the volume increases

the answer is A, on solidification latent heat is given out why the opposite it is release out
Remember that latent heat of fusion of ice is the quantity of heat required to melt 1g of ice at 0 degrees Celsius, or the quantity of heat 1g of ice absorbs to completely melt at 0 degrees Celsius without temperature change.
When ice absorbs this latent heat,
The ice begins to melt.
The mass remains constant, this is because only a nuclear blast can destroy mass.
The volume begins to decrease until a temperature of 4 degrees celsius, this is due to the popular anomalous expansion of water.
I suggest B
