Dimensions of physical quantities

Question

The physical quantity having the same dimensional formula as that of entropy is

Moderate

A

Latent heat
B

Thermal capacity
C

Heat
D

Specific heat

Solution

   $c h a n g e i n e n t r o p y = d S = \frac{h e a t e n e r g y}{t e m p e r a t u r e r a i s e} = \frac{d Q}{T} = J k^{- 1}$

$h e a t e n e r g y Q = (m a s s) L a t e n t h e a t$
   $L = Q / m = J k g^{- 1}$

   $T h e r m a l c a p a c i t y = H = m s = \frac{d Q}{d T} = J k^{- 1}$

   $a m o u n t o f h e a t = Q = J o u l e$

   $s p e c i f i c h e a t c a p a c i t y = s = \frac{Q}{m . d T} = J k g^{- 1} k^{- 1}$
