IMPACT ON THE SOCIETY The kettle has to a certain degree impacted the society. The invention of the electric kettle has directly and indirectly created a vast variety of jobs in numerous industries. Soon after the invention of the automated kettle, in 1958 Instant noodles was invented in Japan. This become quite popular as the kettle made this consumable very simple and efficient to prepare and eat. This lead to a large industry of ‘supermarket convenience foods’ being produced as not only large food processing companies, but correspondingly new companies were created and they invested into the concept, making their own versions and thus creating new jobs. The invention of the kettle furthermore lead to more jobs as hundreds of companies …show more content…

This coil has an electrical resistor which resists the flow of electricity, which in effect converts electrical energy into heat as energy goes through the coil. Due to this, the heat energy produced by the resistor heats up the water within the kettle to boiling point. The heating element is controlled by a bimetallic thermostat, which contains a variable resistor inside it. Integrated at the bottom of the kettle, it consists of a disc of two different metals bonded tightly together, curved in a particular direction. As temperature inside the kettle rises, one metal expands faster than the other, set up in a manner so when the water reaches boiling point, the steam makes contact with the thermostat, causing it to flex in the opposite direction, which in effect pushes a lever that cuts the circuit and switches off the kettle …show more content…

A thermodynamic engineer applies theories of heat and energy transfers to invent practical solutions to technical problems. They design, develop and test and evaluate products and machinery. Thermodynamic engineers contribute to the design of the kettle for they develop inventions designed to improve the way the heating works in a kettle, such as by creating new heating element concepts or overhauls of the interior layout. A bachelor’s degree in a related chemical or mechanical engineering field is required as there is not direct degree for thermodynamics. An undergraduate course called ‘Engineering Thermodynamics’ is available in the University of
