Question

If there are no heat losses, the heat released by the condensation of ‘x’ gm of steam at 100⁰C into water at 100⁰C can be used to convert ‘y’ gm of ice at 0⁰C into water at 100⁰C, Then the ratio of y : x is nearly –

• A. 1 : 1
• B. 2 : 1
• C. 3 : 1
• D. 4 : 1

Answer 1

Answer: (C)

3 : 1

Answer 2

(y × 80) + (y × 1 × 100) = (x × 540)

Ž 180y = 540x

$\frac{y}{x}$ = 3

y : x = 3 : 1
