A well that flows freely without the need for pumping is called an artesian well. This type of well taps into an aquifer that is under pressure, allowing water to rise naturally to the surface. Artesian wells occur when the aquifer is sandwiched between impermeable layers of rock or clay, creating the necessary pressure for the water to flow.
When the well water is under pressure and flows automatically without the need for pumping, it is called an artesian well. This occurs when water from a confined aquifer is trapped between layers of impermeable rock or clay, creating pressure that forces the water to the surface. Artesian wells can provide a reliable and natural source of water, often flowing continuously without mechanical assistance.
i guess its called fluid.....
The state of matter that flows freely is liquid.
A solar heater is called a self pumping system because cold water flows down the panels by itself when hot water rises into the tank.
Gases.
blood flows by the heart pumping

A solar heater is called a self-pumping system because it uses natural convection to circulate water or heat transfer fluid through the system. When the fluid is heated by the sun, it rises naturally, creating a pumping effect without the need for additional mechanical pumps. This self-pumping mechanism helps to save energy and reduces the complexity of the system.
The state of matter that flows freely is a liquid. Liquids are able to take the shape of their container and flow easily due to their molecular arrangement allowing particles to move past one another.
Water flows to the surface in an artesian well without pumping because of natural pressure created by the water being confined in an underground, permeable rock layer sandwiched between impermeable layers. This pressure forces the water upwards until it reaches the surface without any additional assistance.
