Explanation:
It is known that heat (Q) required to change the phase of a given sample of mass m will be as follows.
........ (1)
where,
= latent heat of fusion
Similarly,
= mL_{v}[/tex] ....... (2)
where,
= latent heat of vaporization
As it is known that value of latent heat of fusion of water is 334 J/g and latent heat of vaporization of water is 2260 J/g.
Hence, equating both the equations as follows.
= 
=
= 
= 54.13 g
Hence, we can conclude that 54.13 grams of ice will melt.
Roughness of the surface and weight of the object.
Technically the answer would be a
These are both physical changes can I get a brain list please
