Q. $10 g m$ ice at $0^{\circ} C$ is mixed with $2 g m$ steam at $10 0^{\circ} C$ then final temperature of mixture will be:-

$4 0^{\circ} C$

$6 0^{\circ} C$

$10 0^{\circ} C$

None of these

$Q_{given} < Q_{taken} T < 10 0^{\circ} C$
$Q_{extra} = 1800 - 1080 = 720 C a l .$
$720 = 12 \times 1 \times (100 - T)$
$60 = 100 - T$
$T = 4 0^{\circ} C$

Q. 10gm ice at 0∘C is mixed with 2gm steam at 100∘C then final temperature of mixture will be:-

40∘C

60∘C

100∘C
