sink
Definition
A sink is a basin that is used to collect and drain water. It is typically made of a material that is resistant to water damage, such as porcelain or stainless steel. Sinks have a drain in the bottom that allows water to flow out.
Sinks are used in a variety of settings, including kitchens, bathrooms, laboratories, and factories. In kitchens, sinks are used to wash dishes and food. In bathrooms, sinks are used to wash hands and faces. In laboratories, sinks are used to wash scientific equipment. In factories, sinks are used to wash parts and products.
The design of sinks varies depending on their intended use. Kitchen sinks are typically deeper than bathroom sinks to accommodate large dishes. Laboratory sinks are often made of stainless steel to resist corrosion from chemicals. Factory sinks may be made of concrete to withstand heavy use.

AQA Science Exam Question and Answer
Question:
Explain the concept of water pressure in the context of a sink and how it influences the flow of water from a tap, considering factors such as depth, surface area, and the role of gravity.
Answer:
Water pressure is a fundamental principle that plays a crucial role in the operation of a sink and the flow of water from a tap. It refers to the force exerted by a column of water due to gravity. The pressure increases with depth, as the weight of the water above exerts greater force.
When you open a tap, water flows out because of the pressure difference between the water in the pipes and the atmosphere. As the tap is closer to the ground, the water pressure is higher at the bottom, allowing water to be pushed upward against gravity.
The flow rate of water from the tap is influenced by various factors, including the surface area of the opening, the diameter of the pipe, and any obstructions. A larger surface area or wider pipe allows for a greater volume of water to flow through.
In summary, water pressure drives the flow of water from a tap into a sink. Understanding the relationship between depth, surface area, and pressure is essential for optimising water distribution systems and ensuring efficient water usage in everyday activities.
