Question 572: Thermodynamics & KTG

Question

M grams of steam at 100
o
C is mixed with 200 g of ice at its melting point in a thermally insulated
container. If it produced liquid water at 40
o
C [heat of vaporization of water is 540 cal/g and heat
of fusion of ice is 80 cal/g] the value of M is ____

Accepted Answer

M ÃÂ 540 + M + 60 = 200 ÃÂ 80 + 200 ÃÂ 1ÃÂ (40Ã¢ÂÂ 0)
$$ \Rightarrow $$ 600 M = 24000
$$ \Rightarrow $$ M = 40

Thermodynamics & KTG

M grams of steam at 100 o C is mixed with 200 g of ice at its melting point in a thermally insulated container. If it produced liquid water at 40 o C [heat of vaporization of water is 540 cal/g and heat of fusion of ice is 80 cal/g] the value of M is ____
