One gram of ice is mixed with one gram of steam. After thermal equilibrium, the temperature of the mixture is -
A
00C
B
1000 C
C
550C
D
800C
Answer
1000 C
Explanation
Solution
Heat release when 1gm steam convert into water at 1000C is = mLcond.
= 1 × 536 cal.
heat required to convert ice into water
at 1000C = mLfus. + mSwdq
= (1× 80) + 1 × 1 × 100
= 180 cal
Since 536 cal is greater than 180 cal so partial condensation will take place and the final temperature will be 1000 C.
