It is necessary to determine the specific heat of an unknown object. The mass of the object is 201.0 g. It is determined experim

navik [9.2K]

Mass = 0.201kg
Energy = 15J
temperature change = 10C

Energy(E) = mass(m) × specific heat capacity(c) × temperature change(θ)

we can rearrange this to make specific heat capacity the subject

c = $\frac{E}{m\theta}$

c = $\frac{15}{2.01}$
c =7.46268657
