Question

4B. It turns out that ice is less dense than water. This is why ice floats. Suppose we have a metal pot at 0 ?C and it is completely filled to the brim with uniform solid ice. When the ice melts, and with the resulting water still at 0 ?C, you can predict that

a. some of the resulting water will spill over the edge of the pot

b. the pot will still be perfectly filled

c. the water level in the pot will be a bit lower than it was for the ice

d. while ice melts some of the water must have been above 0 C

C e. both a and d

Explanation / Answer

Ice is less dense than water this means volume occupied by ice is more compared to water at zero degrees.

Water shows the abnormal behavior of contracting when the temperature is increased from zero to four degrees.

So upon converting into the water from ice the volume will decrease.

Hence water level in the pot will be lower than it was for ice.

Answer - C
