Physics Prac

Prac Report Aim: To investigate an galvanic doohickey ( cook) and distinguish on how it functions and to identify any safety features present on the device ( nuke). Equipment: * Microwave * Hammer * Screw Drivers * Pliers system: 1. take away 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 separate parts of the atomize such as the motor, fan, transformer and power supply. 5.Removed the aureole magnets from the power supply. The Microwave Oven A micro-cook is a kitchen putz that was first introduced in 1969 and is used to warmness up loyal victuals. The microwave 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 microw ave works by using microwave radiation syndrome to awaken up the molecules in the food, thus passion the food up itself. Using this method, the browning or baking sweltering of foods does not occur. Microwaves pass microwave radiation through food. Fat, mingy 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 hinge upon on one end and a negative crack on the other) constantly rotates to align with the electromagnetic field. As the molecules rotate, they lease and transfer heat to other molecules causing the food to heat up. There are many ways in w hich an galvanic malfunction can occur with! in a microwave. peerless 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 consignment may start up. Another way to have an galvanic 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
