Correct Answer: Option B

Explanation

mcΔT = Pt → 5 x c x 30 = 2000 x 10 x 60

c = \(\frac{1200000}{150}\)

c = 8000 = 8.0 x \(10^3J/kgºC^{-1}\)

But, Heat capacity C = mass x specific heat capacity

C = 5 x 8000 = 40000 = 4 x (10^4JºC^{-1}\)

(OR) C = \(\frac{2000* 10* 60*}{30}\) = 40,000JºC\(^{-1}\)
