Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or 32 °F (0 °C; 273 K) Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is … Meer weergeven As a naturally occurring crystalline inorganic solid with an ordered structure, ice is considered to be a mineral. It possesses a regular crystalline structure based on the molecule of water, which consists of a … Meer weergeven Ablation of ice refers to both its melting and its dissolution.
