Question

Define pressure and give the common units for pressure.

Short answer

Pressure is the force exerted per unit area. The common units for pressure include: pascal (Pa), bar, atmospheres (atm), kilopascal (kPa), and millimeters of mercury (mmHg or torr).

Step-by-step solution

Defining Pressure

Pressure can be defined as the physical force exerted on an object. It is the amount of force applied per unit area. This quantity is commonly used in the fields of science and engineering.

Identifying units for pressure

There are several units used to measure pressure. Some of the most common ones include\: the pascal (Pa), which is the standard unit of pressure in the International System of Units (SI). Other common units include atmospheres (atm), bar, kilopascal (kPa), and millimeters of mercury (mmHg or torr).
