The dimensional formula for entropy is
Options
- A[ M L T - 2 K - 1 ]
- B[ M L 2 T - 2 ]
- C[ M L 2 T - 2 K - 1 ]
- D[ M L - 2 T - 2 K - 1 ]
Correct answer
C. [ M L 2 T - 2 K - 1 ]
Step-by-step solution
E n t r o p y = h e a t t e m p e r a t u r e ( Δ Q = T Δ S ) [Entropy]= Q T = [ M L 2 T - 2 ] [ K ] = [ M L 2 T - 2 K - 1 ]
