Properties Of Solids And Liquids Question 81
Question: 50 gm ice at 0°C in insulator vessel, 50g water of 100°C is mixed in it, then final temperature of the mixture is (neglect the heat loss) [RPMT 2001]
Options:
A) 10°C
B) $ 0{}^\circ «T _{m}<20{}^\circ C $
C) 20°C
D) Above 20°C
Show Answer
Answer:
Correct Answer: A
Solution:
$ {\theta _{\text{mix}}}=\frac{{\theta _{W}}-\frac{{L _{i}}}{C _{W}}}{2}=\frac{100-\frac{80}{1}}{2}=10{}^\circ C $
