Detailed explanation-1: -Notes: Medium-density Amorphous (MDA) Ice is a new form of ice that was recently discovered by scientists. This ice has same density and structure as water. The ice was created by scientists in a container with stainless steel balls at a-200°C. The MDA ice does not have any ordered structure.
Detailed explanation-2: -“We know of 20 crystalline forms of ice, but only two main types of amorphous ice have previously been discovered, known as high-density and low-density amorphous ices.”
Detailed explanation-3: -The method is applied to amorphous water ice of a large range of densities, between 0.6 g cm−3 and 1.6 g cm−3 to represent low-density and high-density amorphous ices, at 40 K and 140 K. The most stable forms appear for densities in good agreement with experimental data, 0.9–1.0 g cm−3 and 1.1–1.2 g cm−3.
