What is the unit of pressure in the SI system?
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: Learn that the unit of area in the SI system is the square meter (m²).
- Step 5: Combine these two units to define pressure: Pressure = Force / Area.
- Step 6: Therefore, the unit of pressure is newton per square meter, which is written as N/m².
- Step 7: The unit N/m² is also called Pascal (Pa).
- Step 8: Conclude that the SI unit of pressure is Pascal (Pa).
