2gm of steam condenses when passed through 40gm of water initially at 25°C. The condensation of steam raises the temperature of water to 54.3°C. What is the latent heat of steam
Text Solution
Verified by ExpertsThe correct answer is:
A
Let L be the latent heat and using principle of calorimetry.
2L + 2 (100 – 54.3) = 40 × × (54.3 – 25.3)
⇒ ⇒ L = 540.3 cal/gm.
