Question

The amount of heat energy Q,used to heat up a substance depends on its mass m,its specific heat capacity(s) and the change in temprature ∆T of the substance.Using dimensional method,find the expression for s is???​

Answer 1

Answer:

Q=ms∆T

therefore

s=Q/m∆T

or,

since dimesion of S is L2 T-2K-1

Q=ML-2T-2

or, L-2T-2=Q/M

therefore S=Q/MK

Or, S=Q/m∆T ( K= ∆T Change in temp.)
