Secondary Information

Definition

An appliance is a device that is used to perform a specific task, such as cooking food, cleaning clothes, or cooling air. Appliances are typically powered by electricity, but some may also be powered by gas or other fuels.

Appliances are an important part of our everyday lives, and they have become increasingly sophisticated over time. For example, modern refrigerators are now able to adjust their temperature settings automatically, and some washing machines can even detect the type of fabric that is being washed and adjust the washing cycle accordingly.

In science, appliances are often used to perform experiments or to measure physical quantities. For example, a scientist might use a microwave oven to heat a sample of water in order to measure its specific heat capacity.

AQA Science Exam Question and Answer

Question:

Define the term "appliance" in the context of electricity and electrical devices. Explain how electrical appliances work and the importance of safety precautions when using them.

Answer:

  • In the context of electricity, an "appliance" refers to an electrical device or machine designed to perform specific tasks, such as cooking, cooling, or cleaning. Electrical appliances work by converting electrical energy into other forms of energy, such as heat, light, or mechanical motion, to fulfil their intended functions. Safety precautions are crucial when using electrical appliances to prevent electrical shocks, fires, or other hazards. These precautions include proper grounding, using surge protectors, avoiding overloading electrical circuits, and ensuring regular maintenance and inspections to minimise risks associated with electrical usage.
