Specific heat is the amount of heat required to raise the temperature of one kg of mass by 1 kelvin. The SI unit of specific heat capacity is Jkg−1K−1.We know that Q = Cm∆T where Q is heat; C is specific heat; m is mass (in kg); ∆T is change in temperature (in kelvin) ⇒C=
Q
mΔT
T Therefore, SI unit of specific heat capacity is Jkg−1K−1
