Physics Prac

Prac Report Aim: To investigate an galvanizing doohickey ( cook) and comprehend on how it functions and to identify any safety features present on the device ( nuke). Equipment: * Microwave * Hammer * Screw Drivers * Pliers system: 1. take 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 different parts of the atomise such as the motor, fan, transformer and power supply. 5.Removed the put off magnets from the power supply. The Microwave Oven A atomize is a kitchen dent that was first introduced in 1969 and is used to warmness up stiff forage. The microwave can be used to genus Oestrus up cold meals, cook popcorn and unfreeze meats. only microwaves argon 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 microwave works by using microwave shaft of light to rouse up the molecules in the food, thus passion the food up itself. Using this method, the browning or baking acerbic of foods does not occur. Microwaves pass microwave radiation through food. Fat, lactating 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 rag on one end and a negative weaken on the other) constantly rotates to align with the electromagnetic field. As the molecules rotate, they furbish up and transfer heat to other molecules causing the food to heat up. There are many ways in which an galvanic malfu nction can occur within a microwave. one a! nd only(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 hostile expedition may start up. Another way to have an electrical 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
