Electrical Engineering XYZ MCQs

Which of the quantity consists of unit as Pascal:

- Force
- Temperature
- Impulse
- Pressure

Correct answer: 4. Pressure

Explanation:

**Force**: The unit of force is Newton (N), not Pascal. Force represents the interaction that causes an object with mass to change its velocity. Common examples of forces include gravity, friction, and tension.**Temperature**: The unit of temperature can be Kelvin (K), Celsius (°C), or Fahrenheit (°F), depending on the scale used. Pascal is not a unit of temperature.**Impulse**: Impulse is the change in momentum of an object when a force is applied to it over a period of time. The unit of impulse is Newton-second (N·s) or kilogram-meter per second (kg·m/s), not Pascal.**Pressure**: Pressure is defined as force per unit area. The unit of pressure is Pascal (Pa), which is equivalent to one Newton per square meter (N/m²). It represents the amount of force applied perpendicular to the surface of an object per unit area. Common examples include atmospheric pressure, blood pressure, and pressure in fluids.

So, among the options provided, only **Pressure** corresponds to the unit Pascal.
