Steam at 100 ° C is passed into 1 . 1 kg of water contained in a calorimeter of water equivalent 0 . 02 kg at 15 ° C till the temperature of the calorimeter and its contents rise to 80 ° C . The mass of the steam condensed in kg is

Options

  1. A0 . 130
  2. B0 . 065
  3. C0 . 260
  4. D0 . 200

Correct answer

A. 0 . 130

Step-by-step solution

m L + m 100 - 80 = 1.1 × 1 × 80 - 15 + 0.02 × 80 - 15 540 m + 20 m = 71.5 + 1.30 ⇒ m = 0.130
