(20 12? Just after the solar terms in long summer, Jinan was as hot as summer, so Xiaoyun used the refrigerator to make ice cubes to cool down.

(1) mass is the property of matter, which is only related to the amount of matter contained, and has nothing to do with the position, state, shape and temperature of the object, so the mass of water remains unchanged after it becomes ice; Therefore, option B is correct;

(2) The density of water is 1.0× 103kg/m3, and the density of ice is 0.9× 103kg/m3, so the density formed by water becomes smaller, and option C is wrong;

(3) According to the calculation formula of density ρ=mV, V=mρ is deformed, the mass m remains unchanged, the density ρ decreases, and the volume V increases, so option A is wrong.

(4) The specific heat of water is 4.2× 103J/(kg? ℃), the specific heat capacity of ice is 2. 1× 103J/(kg? C), so the specific heat capacity of water becomes smaller, so the D option is wrong;

So choose B.
