If i have Energy Density (U) -> U.Area= F but F.Area = pressure (p) but p must be U . I'm confused! In which cases we can say that energy density is pressure?

Energy density is a measure of the amount of energy stored in a given amount of space. It is often used in physics and engineering to describe the amount of energy per unit volume. Pressure, on the other hand, is a measure of the force applied over a given area. Energy density and pressure are related in that a higher pressure can lead to a higher energy density due to the compression of materials.
The energy density of a material can significantly impact its behavior when placed under pressure. Materials with higher energy density tend to be more resistant to compression and can withstand higher pressures without significant deformation. On the other hand, materials with lower energy density may experience more significant changes in their physical properties when placed under pressure.
The strength of a material is directly related to its energy density. In general, materials with higher energy density have a higher strength, meaning they can withstand greater forces without breaking or deforming. This is because higher energy density materials have stronger chemical bonds and can absorb more energy before reaching their breaking point.
No, increasing pressure does not always lead to an increase in energy density. The relationship between pressure and energy density depends on the material being compressed. In some cases, increasing pressure may lead to a decrease in energy density, such as when a gas is compressed and its volume decreases. In other cases, the energy density may remain constant or only increase slightly with increasing pressure.
The concept of energy density versus pressure is used in various practical applications, such as in the design of hydraulic systems and energy storage devices. Understanding the relationship between energy density and pressure allows engineers to select the most appropriate materials for these applications and ensure that they can withstand the required amount of pressure. It is also essential in fields such as geology and materials science, where the behavior of materials under pressure is of interest.
