Match List – I with List – II and select the correct answer from the codes given below :

List – I (Physical Quantity) List – II (Unit)
A. Pressure 1. Light year
B. Work 2. Joule
C. Temperature 3. Fahrenheit
D. Distance 4. Pascal

Appeared in: UPPSC 2017

Explanation

  • The correct option correctly pairs each physical quantity with its standard or common unit of measurement.
  • Pressure is the force per unit area, measured in Pascals (Pa).
  • Work is a form of energy transfer, measured in Joules (J).
  • Temperature is a measure of thermal energy, and Fahrenheit (°F) is one of the scales used to measure it.
  • A light-year is a specialized unit used to measure vast astronomical distances.

Why Other Options Were Wrong

  • Option A: This option incorrectly matches Pressure with Light year, Work with Fahrenheit, and Temperature with Joule. A light-year is a unit of distance, not pressure. Fahrenheit is a unit of temperature, not work. Joule is a unit of work, not temperature.
  • Option B: This option incorrectly matches Pressure with Joule, Work with Pascal, and Distance with Fahrenheit. A Joule is a unit of work/energy, not pressure. A Pascal is a unit of pressure, not work. Fahrenheit is a unit of temperature, not distance.
  • Option D: This option incorrectly matches Pressure with Fahrenheit, Work with Light year, and Temperature with Pascal. Fahrenheit is a unit of temperature, not pressure. A light-year is a unit of distance, not work. A Pascal is a unit of pressure, not temperature.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Matching physical quantities with their corresponding units of measurement as background academic context rather than a clinical decision trigger.
  • While this is a physics question, these concepts are foundational in healthcare.
  • Pressure: Blood pressure is a vital sign, measured in millimeters of mercury (mmHg), a unit of pressure. Ventilator pressures are measured in cmH₂O.
  • Work/Energy: The body's metabolic processes involve energy, measured in calories or kilojoules (related to Joules). Understanding energy is key to dietetics and patient nutrition.
How to Approach the Question
  • This is a 'Match the Following' question. The goal is to create correct pairs from two lists.
  • Start with the quantity you are most confident about. For example, you might know that 'Work' is measured in 'Joules'. This is pair B-2.
  • Look at the options. Only one option, (C), contains the pair B-2. This strongly suggests it is the correct answer.
  • To confirm, check the other pairs in that option: A-4 (Pressure-Pascal), C-3 (Temperature-Fahrenheit), and D-1 (Distance-Light year).
  • All these pairs are correct, confirming that the chosen option is the right answer.
  • This method of using one known pair to eliminate other options is a very efficient strategy for matching questions.
Concept Tested & Keywords
