What is the specific heat of a substance that has a mass of 35.0 g and requires 625.0 calories to raise its temperature by 25.0C

We know that

Q=m. s. t, where Q = Heat, s = Specific heat of the substance, t=temperature (Difference in temperatures)

=>s = Q/m. t

=>s=525 / (25X15)

=>s=525/375

=>s=1.4 cal/g/0c

Specific heat of the substance is 1.4 cal/g/0c.
