Physics Prac

Prac Report Aim: To investigate an voltaic doohickey ( cook) and answer for on how it functions and to identify any safety features present on the device ( nuke). Equipment: * Microwave * Hammer * Screw Drivers * Pliers regularity: 1. upstage the power cord at the back of the atomize. 2. Removed the door of the zap. 3.Removed the outer cover of the micro-cook. 4. Began to deprive and remove another(prenominal) parts of the nuke such as the motor, fan, transformer and power supply. 5.Removed the fence magnets from the power supply. The Microwave Oven A vaporize is a kitchen dig that was first introduced in 1969 and is used to warmness up real diet. The micro-cook can be used to genus Oestrus up cold meals, cook popcorn and unfreeze meats. only microwaves atomic number 18 built in nearly the exact uniform way. With a timer on the front, a power cord at the back and a sealable compartment in which to erupt food in. A microwav e works by using microwave radiation to affectionateness up the molecules in the food, thus passion the food up itself. Using this method, the browning or baking warm of foods does not occur. Microwaves pass microwave radiation through food. Fat, alter and other molecules in the food absorb the energy from microwaves in a process called dielectric heating.

Dielectric heating is when a polar molecule (a molecule that has a positive raise up on one end and a negative wear down on the other) constantly rotates to align with the electromagnetic field. As the molecules rotate, they cling and transfer heat to other molecules causing the food to heat up. There are many ways in which an galvanic malfunction can occur within a ! microwave. one(prenominal) way is by placing metals into the microwave. When you place metals inside a microwave and turn it on, sparks will begin to appear inside the microwave which may go out of control and a ship may start up. Another way to have an electric malfunction is when the power cord is damaged. If the fan inside the microwave stops, another...If you want to get a full essay, order it on our website: OrderEssay.net
