Vedclass · Answer

(B) According to the mass-energy equivalence principle,$E = mc^2$,where $E$ is energy,$m$ is mass,and $c$ is the speed of light.When water is cooled to form ice,it releases latent heat to the surroundings,meaning the system loses energy ($E$ decreases).Since the total energy of the system decreases,the mass of the system must also decrease to satisfy the equation $m = E/c^2$.Therefore,the mass of the water decreases when it turns into ice.

If mass-energy equivalence is taken into account,when water is cooled to form ice,the mass of water should
