Heat is supplied uniformly at the rate of 100W to 1.0 x 10-2kg of a liquid for 20 seconds. If the temperature of the liquid rises by 5oC, then the specific heat capacity of the liquid is

  • A. 2.0 x 10\(^2\)Jkg\(^-1\)K\(^-1\)
  • B. 2.0 x 10\(^2\)Jkg\(^-1\)
  • C. 4.0 x 10\(^4\)Jkg\(^-1\)K\(^-1\)
  • D. 4.0 x 10\(^4\)Jkg\(^-1\)

Correct Answer: C. 4.0 x 10\(^4\)Jkg\(^-1\)K\(^-1\)
