1.

If DeltaH=mL, where m is mass of body. DeltaH= total thermal energy supplied to the body L= latent heat of fusion. Find the dimensions of latent of fusion.

Answer»

`[ML^(2)T^(-2)]`
`[L^(2)T^(-2)]`
`[M^(0)L^(0)T^(-2)]`
`[ML^(0)T^(-1)]`

SOLUTION :(B) `DeltaH=mL :[L]=([ML^(2)T^(-2)])/([M])=[L^(2)T^(-2)]`
