Q: The unit of pressure in SI is:
Solution:
The SI unit of pressure is Pascal (Pa), defined as one newton per square meter (N/m²).
Steps: 7
Show Steps
Step 1: Understand what pressure is. Pressure is the force applied over a certain area.
Step 2: Know the unit of force in the International System of Units (SI), which is the Newton (N).
Step 3: Understand that pressure is calculated by dividing force by area.
Step 4: The area is measured in square meters (m²).
Step 5: Combine these units: Pressure = Force / Area = Newton / square meter = N/m².
Step 6: The unit N/m² is also called Pascal (Pa).
Step 7: Therefore, the SI unit of pressure is Pascal (Pa).
