Physics · Binding energy per nucleon and its variation with mass number, nuclear fission and fusion
If mass-energy equivalence is taken into account, when water is cooled to form i
If mass-energy equivalence is taken into account, when water is cooled to form ice, the mass of water should
- A. increase
- B. remain unchanged
- C. decrease
- D. first increase then decrease
Step-by-step solution
According to mass-energy equivalence (E=mc²), when water cools and freezes into ice, it releases latent heat (energy) to the surroundings. This loss of energy corresponds to a loss of mass, so the mass decreases. Although the change is extremely small, theoretically the mass decreases.
