Question

Which one of the following is used as refrigerant to preserve biological materials and also in cryosurgery​

Answer 1

Answer:

Liquid nitrogen is used as a refrigerant to preserve the  biological specimens because of its low temperature (−196 degrees  ) that does not cause cell breakdown or affect any other cellular mechanisms.

Explanation:

Cryosurgery is a treatment that uses extreme cold produced by liquid nitrogen or argon gas to destroy cancer cells and abnormal tissue. It is a local treatment, which means that it is directed toward a specific part of your body.

Answer 2

Answer:

Liquid nitrogen is used as refrigerant to preserve biological materials and also in cryosurgery​

Explanation:

• Among the cryogenic liquids is liquid nitrogen. Liquid nitrogen is mostly used as a refrigerant, similar to dry ice.
• Liquid nitrogen, which has a boiling point of -196C, is used for a number of purposes, including as a computer coolant, in medicine to remove warts, undesirable skin, and precancerous cells, and in cryogenics, which is the study of how materials respond to extremely low temperatures.
• In actuality, improper handling of liquid nitrogen is harmful. If used or spilled in a confined space, liquid nitrogen, which is colourless, odourless, and tasteless, can induce frostbite or cryogenic burns.
• In many cooling and heating applications, liquid nitrogen is a form of the element nitrogen that is cold enough to exist in a liquid state.
