Question

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

• A. Increase
• B. Remain unchanged
• C. decrease
• D. First increase and then decrease

Answer 1

The correct option is C decrease

As we know that when water is converted into ice then it releases

energy to the atmosphere, in other words, it can be said that

it releases some mass to the atmosphere because mass and

energy are equivalent.

So option C is correct that mass will decrease.
