Non-stick frying pans are one of the most common kitchen utensils today. Frying pan is mostly used for cooking. The non stick frying pans are made of two components, the metal body and the Non Stick layer. Actually the surface of the non stick frying pan is coated with a layer of oil or fat when the pan is in use. The layer of oil has four functions: it lubricates the surface; increases contact between the food and the pan; acts as a thermal mass to reduce the cooking time; and can be increases flavor and color.
Frying pans were made of cast iron. Cast iron is mostly used for outdoor cooking. Now frying pans are made from metals, such as aluminium and Stainless steel. Frying pans can be also made of copper.
History
The first frying pan was made of a cooper. And it first use in Mesopotamia and Greece. In Greece they were called “Teganon” and in Rome they called patella. The first non stick frying pan was introduced by DuPont in 1956. The product still has some limitation because the coating is poor and this make the standard of the kitchen utensils.
Radioactivity
Radioactivity is a particle that released from nuclei as the result from the unstable nuclear. Because the nucleus it’s a conflict experiences that intense between the two strongest forces in nature so there are many nuclear isotopes that unstable and emit some radiations.
Using a frying pan
Non stick frying pan can be use for many foods that fried. The function is when we cooked food that a little wet; the parts of the foods not stick in the frying pan. Non stick frying pan is different from an ordinary frying pan. The non stick frying pan has two layers which are the metal body and the Non Stick layer and the ordinary frying pan has one layer which is the ...

Heat the contents of the pan over a low flame and bring it to a boil.
To begin with, people browsing any type of book notice its pictures first. This cookbook has colorful pictures of some of the dishes fully prepared. The pictures offer the person cooking an idea of whether he or she wants to make that recipe. They also illustrate what the dish should look like, or closely resemble, when it is complete. However, the book
The experimenter cracked an egg into a clean bowl and added 1/10 spoon of salt to the bowl. The experimenter used the egg beater at the lowest setting to stir the egg until it became a pale yellow and homogeneous fluid. The experimenter then added water into the well stirred egg. The volume of water was about 1/6 of the volume of the beaten egg. Starting the stopwatch, the experimenter used the egg beater to stir the mixture of egg, salt, and water for 20 seconds. After preparing the egg, the experimenter filled the bottom of the frying pan with a thin layer of olive oil and placed it on the cooking stove. The experimenter cooked the oil over medium heat for 1 minute. The experimenter then poured the beaten egg into the frying pan and set the power of the cooking stove to low heat. The experimenter stirred the egg constantly until it became fluffy and no liquid was present in the pan.
To understand what a radioactive isotope is a basic understanding of the atom is necessary. Atoms are comprised of three subatomic particles : protons, neutrons and electrons. Protons and neutrons bind together to form the nucleus of the atom, while the electrons surround and orbit the nucleus. Protons and electrons have opposite charges and therefore attract one another (electrons are negative and protons are positive, and opposite charges attract), and in most cases the number of electrons and protons are the same for an atom (making the atom neutral in charge). The neutrons are neutral. Their purpose in the nucleus is to bind protons together. Because the protons all have the same charge and would naturally repel one another, the neutrons act as "glue" to hold the protons tightly together in the nucleus.

A radioisotope is an isotope that emits radiation as it has nuclear instability(Prostate Cancer; Fusion imaging helps target greater doses of radiation).Those who are not too familiar with radioisotopes may think their use is for harmful radiation, nuclear weapons, and the possibility of turning into a giant, raging, green monster. However, there are much more positive uses for radioisotopes. There have been many medical advances thanks to the benefit and practice of radioisotopes in nuclear medicine. These advances have been able to diagnose and treat a variety of diseases.
Beta radiation/emission – Beta particles are electrons (0-1e) that have been released from the nucleus of a radioactive atom when a neutron decays into a proton and electron. Beta decay/emission happens when the neutron to proton ratio is too high due to excess neutrons. 10n 11p + 0-1e (mass is still conserved as well as number of protons.)
When we place two objects with different temperatures in contact with each other, the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while others make poor conductors of heat or excellent insulators. Silver, copper, and gold make excellent conductors of heat. Foams and plastics make good insulators of heat but make poor conductors. Last night for dinner, I made myself a grilled cheese sandwich and a bowl of tomato soup. I heated the soup faster than I cooked the sandwich so I poured the hot soup into a bowl and finished cooking the sandwich. Once I was done cooking, I gabbed the soup bowl and burned my hand. The heat from the soup made the bowl hot. This is an example of conduction.

Metals are utilized in a majority of different ways, for example: gold is used to create jewelry, iron is used to create strong sturdy structures like bridges and steel is used to make long lasting items such as pots and pans.
When I first learned to cook about six years ago, there were no magazine articles or books in bookstores explaining how to cook; there were only cookbooks with recipes for one to decipher. Today, the articles and books that explain how to cook are minimal. Not everyone can compete with Julia Child in cooking gourmet food with the menu devised in our minds without referring to cookbooks, but many of us can learn to cook effectively. A step-by-step process should be followed to learn how to cook successfully.
The first method of cooking discovered was roasting. It was discovered when someone accidentally cooked a piece of meat over an open fire. The second method of cooking, boiling, was not accidental though. The process was carefully thought over and was carried out using tools specially made for boiling. Learning to cook was really beneficial for our health, and a big step forward culturally.
Each and every year millions of people become sick because of food poisoning and other food related illnesses. Many of these illnesses can easily be prevented by properly cooking and handling food in the kitchen. Unfortunately, many people around the world are unaware of the consequences that can occur from contaminated and undercooked food. It is important for every individual who is planning on making a meal in their life (virtually everyone) to understand how to properly prepare their meal.
