Answer

Brief Explanations:

At equilibrium, the forward and reverse processes occur at the same rate. In the phase - change equilibrium of water ($H_2O(s)\rightleftharpoons H_2O(l)$), the rate of melting of ice ($H_2O(s)$) is equal to the rate of freezing of water ($H_2O(l)$). As a result, the mass of $H_2O(s)$ and the mass of $H_2O(l)$ do not change over time and remain constant.

Answer:

  1. The mass of $H_2O( \ell)$ and the mass of $H_2O(s)$ each remain constant.
