Question

Which of the following is the SI unit of pressure?

SUBHANI · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Pressure and its units
 **Related Topics**: SI units, Force, Area
 **Prerequisites**: Understanding of pressure as force per unit area.
## SOLUTION PATHWAY
**Given Information**:
  The question asks for the SI unit of pressure.
**Method & Steps**:
 1. Define pressure:
  Reasoning: Pressure is defined as force applied per unit area.
  Formula/Rule: $Pressure = \frac{Force}{Area}$
 2. Determine the SI units of force and area:
  Working: The SI unit of force is the Newton (N), and the SI unit of area is the square meter ($m^2$).
  Key Point:  Substituting the SI units into the pressure formula gives the SI unit of pressure.
 3. Calculate the SI unit of pressure:
  Result: $Pressure = \frac{Newton}{m^2} = \frac{N}{m^2} = Pascal (Pa)$
  Verification: The Pascal (Pa) is indeed the SI unit of pressure.
 ## OPTION ANALYSIS
A :x: Newton (N) is the SI unit of force, not pressure.
B :x: Joule (J) is the SI unit of energy, not pressure.
C ✓: Pascal (Pa) is the SI unit of pressure, defined as N/m².
D :x: Watt (W) is the SI unit of power, not pressure.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing pressure with force or energy: Remember the definition of pressure as force per unit area.
  2.Using incorrect units: Always use SI units when working with physics problems unless specified otherwise.
 **Quick Tips**:
  1.Remember the formula: Pressure = Force/Area
  2.Associate Pascal (Pa) with pressure.
