INTRODUCTION
A microwave oven is a kitchen electrical appliance that passes an electromagnetic wave with an extremely high frequency that is used to cook food. By absorbing energy from water molecules in the food, heat is produced, and therefore cooking can be performed. Besides cooking, microwave oven can be used to warm up food as well as used to defrost frozen food. Invention of microwave ovens definitely saves us a lot time and electricity.
During this week laboratory class, we have been assigned to conduct tests on various models of microwave ovens. We tested on the abilities of three models of microwave ovens which are National, Sharp and LG in heating water, reheating mushroom soup, defrosting meat, cooking meat and finally in cooking rice. In addition, we have assessed the ease of use of those three microwave ovens too while carrying out the testing regarding their functions.
Moreover, in order to test how well the microwave ovens have performed, we have measured the temperature of the water, mushroom soup as well as the meat. The temperature of water and mushroom soup has been measured using a thermometer whilst the temperature of the meat has been measured using a digital meat thermometer. A meat thermometer is designed specially to measure the internal temperature of meat and other cooked foods.
Results obtained from the evaluation of the features found on National, Sharp and LG microwave ovens as well as the results we get regarding the microwave ovens’ abilities and performances have been tabulated. By doing so, it is easier for us to make comparison based on the tables.

To sum up, it is important for us to understand the basic principles of microwave cooking in order to ensure that food will be properly and safely cooked.
2. What are the advantages of microwave ovens to conventional ovens?
There are many advantages of microwave ovens as compared to conventional ovens. Firstly, conventional oven cooks at a slower pace, whereas the cooking time of microwave is short. Besides, because of the speed of microwave, cooking is more energy efficient as the energy heats only the foods, not the oven compartment. Furthermore, foods cooked by using microwave oven cause less destruction of nutrients than using a conventional oven. In fact, foods cooked in a microwave oven may keep more of their vitamins and minerals because foods cook faster and require no added water.
We must first begin the today’s lab by connecting the thermometer that digitally detects surrounding temperature to the Lab Pro Interface located on the computer via...
Experimental Summary: First, my partner and I put the marshmallow and cheese puff on T-pins and used the Electronic Balance to measure the mass of each of them. Next, we put 100 mL of water in the 100 mL Graduated Cylinder and poured it into the 12 oz. soda can. We measured the temperature of the water with the thermometer. After
The objective of this experiment was to identify a metal based on its specific heat using calorimetry. The unknown metals specific heat was measured in two different settings, room temperature water and cold water. Using two different temperatures of water would prove that the specific heat remained constant. The heated metal was placed into the two different water temperatures during two separate trials, and then the measurements were recorded. Through the measurements taken and plugged into the equation, two specific heats were found. Taking the two specific heats and averaging them, it was then that
- Temperature was measured after and exact time i.e. 1 minute, 2 minutes, 3 minutes.
By exposing the chocolate and the cookies before the light and heat of the 60-watt light bulb, the students will be able to progressively observe the process of the material melting and make records at every stage of the experiment. Using the 15 seconds step, the students can identify the melt temperature and time of the chocolate under the lab conditions as well as make and analyze their records in the final part of the experiment. The experiment is expected to establish, which of the chocolates and cookies melt faster, and make conclusions about the influence of the consumables ingredients on their physical properties. This corresponds with the TEK 112.11 (5B) procedure, which allows students to “observe, record, and discuss how materials can be changed by heating or
In these commentaries, Schwarcz also answers questions that people and the media have and offer advice to people. For example, a listener asked “How long one should allow microwaved food to stand after cooking to ‘allow the microwaves to escape?” He responded by describing how the food on the inside is cooked through the heat transfer from the exterior, which allows the food to finish cooking. Additionally, it is essential to leave the food to stand for a few minutes. However, this does not allow the microwaves heat to leave, but for the interior to finish cooking as well as the exterior. If you don’t leave the food to settle there for a few minutes than it will leave the cooking process incomplete.
For this experiment, you will need 3 - ceramic bar magnets numbered 1 – 3 for identification purposes, 48 - 5/16” steel flat washers, tongs, goggles, gloves, stove, pot with boiling water, freezer, cooking thermometer, and freezer thermometer. Place the three magnets in the freezer overnight so that they reach a freezing temperature of between 0° - 32°. A freezer thermometer was used to verify temperature. After the magnets have reached the desired temperature, then place two even stacks of steel washers next to each other on a flat surface. Using one fro...
They might not use herbs. They might prefer quick recipes using commercial mixes and a microwave. For that category of people, this cookbook is more of a hindrance. But typically, commercial mixes have a great number of unhealthy preservatives, and some doctors declare microwaves to be harmful to the user. As a result, the cookbook supports keeping its users informed of the nutrients they consume and has minimal microwave use involved.
One of the most important things in caliometry is the caliometer. This is a device used to measure the quantity of heat in a reaction. There are many different types of caliometers, some are used to measure the heat capacity of materials, and others measure the aspects the heat generates by new or untested reactions, heat of combustion and burn rates. One type of caliometer is reaction caliometers. These measure heat energy released or absorbed during a reaction that occurs inside the caliometer. Bomb caliometer are used to measure heat of combustion of a particular reaction. Differential scanning caliometers heat flow into a sample is usually measured differentially. A popular caliometer used in biochemistry is called the isothermal titration caliometer. In this caliometer the heat of the reaction is used to follow a titration experiment. It is used in biochemistry because it t facilitates determination of substrate binding to enzymes. Other caliometers that are sometimes used are x-ray micocaliometer, and high-energy particle caliometer. These two caliometers are not as often used, but can still be included in the different types. It is apparent that there are many different types of caliometers and some are used more commonly than others
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.
In conclusion, cooking has evolved as technology has developed. But in the grand scheme of things we still have the same methods. Cooking helped the advancement of the human brain and the advancement of human teeth and our digestive tracts. Today we have restaurants, grocery stores, microwaves, and ovens. And all we started off with was a fire and a piece of meat with a stick stuck through it. Cooking was, is, and will be a vital part of the human life.
The microwave is a prime example of technology making us happy. If we were to get rid of the microwave, many people would be angry because it is a very helpful and time saving device. If there was no microwave people would not be able to defrost the ground meat they forgot to leave out, nor would they be able to cook a hot pocket for lunch when they were short on time. Some people believe that items that are efficient make society happy.
People all around the world are busy. Busy with work, school and other extra activities. No one ever has time to cook, so families are always going out to eat at a restaurant. This essay will include comparison between eating at home and eating at a restaurant in terms of the price, cleanliness, taste and service.
