The unit of pressure in the SI system is:
Correct Answer: Pascal (Pa)
- Step 1: Understand that pressure is a measure of force applied over an area.
- Step 2: Know that the SI system is a standard system of measurement used worldwide.
- Step 3: Learn that the unit of force in the SI system is the newton (N).
- Step 4: Recognize that area is measured in square meters (m²).
- Step 5: Combine these two concepts: pressure is defined as force (in newtons) divided by area (in square meters).
- Step 6: Therefore, the unit of pressure in the SI system is called Pascal (Pa), which is equal to one newton per square meter (N/m²).
