Final answer:
True, cryosurgery is a procedure that uses extreme cold temperatures to destroy tissue, utilizing cryogenic liquids such as liquefied nitrogen.
Step-by-step explanation:
Cryosurgery is indeed the use of cold temperatures to destroy tissue. This procedure utilizes very cold temperatures provided by liquefied gases like nitrogen to selectively target and destroy abnormal or diseased tissue with minimal loss of blood. Cryogenic liquids, which have applications in various fields, play a crucial role in this medical technique. For example, liquefied nitrogen has a boiling point of 77 K at 1 atmosphere and can be used to preserve biological materials, such as semen for artificial insemination, in addition to its use in cryosurgery.
Placing food in a refrigerator at standard refrigeration temperatures does not necessarily kill bacteria on the food. Instead, it slows down the growth of bacteria, helping to preserve the food for a longer time than if left at room temperature.
