For iso thermal ( constant - temperature) process pV = constant ,
Pressure is inversely proportional to the volume and the graph is a hyperbola
curve 6------>4------->1
The process shows the isothermal process.
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure is the pressure relative to ambient pressure. Various units are used to express pressure.
Pressure is defined as the physical force exerted on an object. The applied force is normal to the surface of the object per unit area. The basic formula for pressure is F/A (force per unit area). The unit of pressure is Pascal (Pa).
