Properties Of Solids And Liquids Question 487
Question: A beaker is completely filled with water at 4°C. It will overflow if [EAMCET 1992; BHU 1994; AFMC 2005]
Options:
A) Heated above 4°C
B) Cooled below 4°C
C) Both heated and cooled above and below 4°C respectively
D) None of the above
Show Answer
Answer:
Correct Answer: C
Solution:
Water has maximum density at 4°C, so if the water is heated above 4°C or cooled below 4°C density decreases i.e. volume increases. In other words, it expands so it overflows in both the cases.
