Hi. Consider a solid body placed in vacuum. How much is its pressure? Can we describe this body using thermodynamics if its pressure is zero?
Pressure is defined as the amount of force exerted on a unit area of a surface. In other words, it is the force per unit area.
The pressure of a solid body can be calculated by dividing the force exerted on the body by its surface area. The formula for pressure is P = F/A, where P is pressure, F is force, and A is surface area.
Yes, pressure can affect the shape of a solid body. When an external force is applied to a solid body, it exerts pressure on the body. This pressure can cause the body to deform or change its shape.
The pressure of a solid body increases with depth. This is because the weight of the body above pushes down on the body below, increasing the force and thus the pressure.
Examples of pressure on a solid body in everyday life include the weight of a stack of books on a table, the pressure exerted by a person's feet on the ground while standing, and the pressure of water on the walls of a swimming pool.
