A can was filled with crushed ice, sealed, and massed. The ice was melted by slowly warming the can and its contents. No water vapor escaped and no air entered the can.
If the can is then massed again after the ice has melted, what is the best prediction of the mass?
The mass would be the same.
The mass would be more.
The mass would be less.
It is impossible to predict without more information.

According to the law of conservation of mass:
mass is lost only in chemical changes.
mass is lost only in physical changes
total mass stays the same in changes of state
only energy is lost in changes of state
According to the law of conservation of energy:
energy is not absorbed or released in changes of state
energy is not transferred during changes of state
energy is not created or destroyed in changes of state
a substance has the same energy before and after a change of state

created
destroyed
released
absorbed
