Question

Temperature can be expressed as derived quantity in terms of:

• A. length and mass
• B. mass and time
• C. length, mass and time
• D. None of these

Hint:

SI base quantities include textbflength, mass, time, electric current, temperature, amount of substance, and textbfluminous intensity. Derived quantities are formed using these, not vice versa.

Answer 1

The Correct Option is D

Step 1: Recall the classification of physical quantities. Physical quantities are classified into:

Fundamental (base) quantities
Derived quantities
Step 2: Identify the nature of temperature. Temperature is one of the seven fundamental (base) quantities in the SI system. It is independent and is not derived from length (L), mass (M), or time (T). Step 3: Check the given options.

(A) Length and mass — incorrect
(B) Mass and time — incorrect
(C) Length, mass and time — incorrect
(D) None of these — correct ✔
Step 4: Final conclusion. Since temperature is a fundamental quantity, it cannot be expressed as a derived quantity in terms of L, M, and T. \[ \boxed{\text{None of these}} \]
