  • A 7.53 x 105 Jkg\(^{-1}\)
  • B 7.53 x 10-2Jkg\(^{-1}\)
  • C \(7.53 \times 10^{4}\)Jkg\(^{-1}\)
  • D 7.53 x 10-3Jkg\(^{-1}\)
Correct Answer: Option C
Explanation:
Quantity of heat = mass(m) × specific latent heat (L)
Q = mL
L = \(\frac{Q}{m}\)
= \(\frac{1.13 \times 10^{6}}{15}\)
= \(7.53 \times 10^{4}\)Jkg\(^{-1}\)
