Question

what do you mean by pressure and give its units​

Answer 1

Pressure is an expression of force exerted on a surface per unit area. The standard unit of pressure is the pascal (Pa), equivalent to one newton per meter squared (N/m 2 or N. ... As the amount of gas increases, assuming the volume of the chamber and the temperature remain constant, the pressure increas

Answer 2

Pressure is an expression of force exerted on a surface per unit area. The standard unit of pressure is the pascal (Pa), equivalent to one newton per meter squared (N/m 2 or N · m -2). Alternatively, pressure can be measured in dynes per centimeter squared (dyn/cm 2 or dyn · cm -2). To convert from pascals to dynes per centimeter squared, multiply by 10. Conversely, multiply by 0.1.
