The correct answer is A. Dry ice is solid carbon dioxide. It is a white, odorless, and non-flammable solid that is used as a refrigerant and in dry ice blasting. Dry ice sublimates at -78.5\u00c2\u00b0C, which means that it changes directly from a solid to a gas without going through a liquid phase. This makes it ideal for use in applications where it is important to keep things cold without getting them wet.<\/p>\n
Option B, crystalline NaCl, is table salt. It is a white, crystalline solid that is used as a food additive and in many industrial processes. Option C, ice frozen at -50\u00c2\u00b0C, is simply ice that has been frozen to a very low temperature. Option D, solid H2O, is water ice. It is a colorless, odorless, and tasteless solid that is found in nature in the form of glaciers, snow, and ice cubes.<\/p>\n","protected":false},"excerpt":{"rendered":"
