Properties Of Solids And Liquids Question 549
Question: Mercury is poured in a U tube. Level of mercury on one side is $ h _{1} $ at temperature $ \text{5}{{\text{0}}^{\text{o}}}\text{C} $ and level of mercury on the other side is $ h _{2} $ at temperature $ \text{10}{{\text{0}}^{\text{o}}}\text{C} $ Then
Options:
A) $ h _{1}=h _{2} $
B) $ h _{1}<h _{2} $
C) $ h _{1}>h _{2} $
D) $ h _{2}=2h _{1} $
Show Answer
Answer:
Correct Answer: C
Solution:
Density of liquid decreases with increase in temperature and h$ h\alpha \frac{1}{p} $ Hence level $ f’( x )=e^{x}( x-1 )( x-2 )<0 $ will be more than $ h _{1} $
