A zinc has a heat capacity of 40 J/K, what is the mass of the zinc, given that the specific heat of zinc is 380 J/kg k
A
0.11kg
B
0.12kg
C
0.13kg
D
0.14kg
Verified Correct Answer: A.
Physical Principles & Numerical Solution
Heat capacity (o) = mass (kg) specific heat of a substance (C2)
i.e Q = MC
where Q = 40 J/L, m = ?(380 J/Kgk)
40 = m × 380
m = 0.11kg (Approx)
