Dimensional formula of $$\Delta Q$$ heat supplied to the system is given by

A$$[{ M }^{ 1 }{ L }^{ 2 }{ T }^{ -2 }]$$
Correct Answer
B$$[{ M }^{ 1 }{ L }^{ 1 }{ T }^{ -2 }]$$
C$$[{ M }^{ 1 }{ L }^{ 2 }{ T }^{ -1 }]$$
D$$[{ M }{ L }^{ 1 }{ T }^{ -1 }]$$

Solution

Heat has the same dimesnsions as energy which has the same dimensions as force times distance. Hence the answer is $$ {[{M}{L}{T}^{-2}]}{[{L}]}={[{M}{L}^{2}{T}^{-2}]} $$.
