Question

10 gm of ice at 0⁰C is mixed with 10 gm steam at 100⁰ in a container of negligible heat capacity. Amount of steam in the mixture after some time will be (S_w = 1 cal/gm⁰C, L_v = 540 cal/gm, L_f = 80 cal/gm) –

• A. 0 gm
• B. $\frac{20}{3}$gm
• C. $\frac{10}{3}$gm
• D. None of these

Answer 1

Answer: (B)

$\frac{20}{3}$gm

Answer 2
