The correct answer is D. Freon.<\/p>\n
Freon is a common refrigerant in domestic refrigerators. It is a colorless, odorless gas that is used to cool the air inside the refrigerator. Freon is a chlorofluorocarbon (CFC), which means that it contains chlorine and fluorine atoms. CFCs are very effective at cooling, but they also have a negative impact on the environment. CFCs are released into the atmosphere when they are used in refrigerators and other appliances. Once they are in the atmosphere, CFCs break down and release chlorine atoms. These chlorine atoms react with ozone molecules in the stratosphere, which helps to protect the Earth from harmful ultraviolet radiation. As a result of the release of CFCs, the ozone layer has been depleted, which has led to an increase in the amount of ultraviolet radiation reaching the Earth’s surface. This increase in ultraviolet radiation has been linked to an increase in skin cancer and other health problems.<\/p>\n
Neon, oxygen, and nitrogen are all gases that are found in the air. They are not used as refrigerants in domestic refrigerators because they are not effective at cooling. Neon is a noble gas, which means that it is very stable and does not react with other elements. Oxygen and nitrogen are both reactive gases, but they are not effective at cooling because they do not have the necessary properties to absorb heat.<\/p>\n","protected":false},"excerpt":{"rendered":"
