10-1.Thermometry, Thermal Expansion and Calorimetry
easy
A beaker is filled with water at $4\,^oC$. At one time the temperature is increased by few degrees above $4\,^oC$ and at another time it is decreased by a few degrees below $4\,^oC$. One shall observe that:
A
the level remains constant in each case
B
in first case water flows while in second case its level comes down
C
in second case water over flows while in first case its comes down
D
water overflows in both the cases
Solution
water expands on both sides of $4\,^oC$.
