Question

The CGS unit of specific heat capacity is:

• A. $Jk{g}^{-1}{K}^{-1}$
• B. $calk{g}^{-1}{K}^{-1}$
• C. $kJk{g}^{-1}{}^{\circ }{C}^{-1}$
• D. $cal{g}^{-1}{}^{\circ }{C}^{-1}$

Answer 1

The correct option is D $cal{g}^{-1}{}^{\circ }{C}^{-1}$

Specific heat capacity is given by:
$s=\frac{Q}{m\Delta T}$
where:
$Q:$ Heat transferred
$m:$ Mass of material
$\Delta T:$ Change in temperature

The CGS unit of specific heat capacity is:
$cal{g}^{-1}{}^{\circ }{C}^{-1}$
The SI unit of the same is:
$Jk{g}^{-1}{K}^{-1}$
