Answer:
Step-by-step explanation:
A physical change does not change the chemical composition of a substance.
A physical change could be :
1) Melting
2) Freezing
3) Evaporation
4) Condensation
In physical change what changes is just the state.
It could be from liquid to gas, from gas to liquid and from gas to solid.
In physical changes the composition does not change neither the chemical composition.
After the physical change the mass remains the same.
Hence the mass remains the same after a physical change.
The mass is thus 8 g after the physical change.
