Q: What is the unit of pressure in the SI system?
Solution:
The SI unit of pressure is Pascal (Pa), defined as one newton per square meter (N/m²).
Steps: 8
Show Steps
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).
