A) \[M{{L}^{2}}{{T}^{-2}}\]
B) \[M{{L}^{-2}}{{T}^{-2}}\]
C) \[{{M}^{0}}L{{T}^{-2}}\]
D) \[{{M}^{0}}{{L}^{2}}{{T}^{-2}}\]
Correct Answer: D
Solution :
Latent heat L is the amount of heat energy H required to change the state of unit mass without producing any change in temperature. Thus \[L=\frac{H}{m}\] \[\therefore \]Dimensions of \[L=\frac{M{{L}^{2}}{{T}^{-2}}}{M}={{L}^{2}}{{T}^{-2}}={{M}^{0}}{{L}^{2}}{{T}^{-2}}\] Hence, the correction option is [d].
