(a)
Interpretation: The comparison needs to be done between the volumes of 1 g of ice at
Concept Introduction: If water freezes, it tends to expand. Water is the only liquid that expands on freezing. Thus, its solid state has a lower volume than the liquid state of the same amount.
(a)
Explanation of Solution
The mass of both ice and liquid water is the same which is 1 g at
Therefore, 1 g of ice at
(b)
Interpretation: The comparison needs to be done between 1 g of liquid water at
Concept Introduction: Solids have compact structures thus; they have definite volumes. The volume of liquid is also defined but in the case of gases, volume is not definite, it can take up the volume of the entire container in which it is placed. Thus, the volume of gases is larger than the volume of liquid of the same mass.
(b)
Explanation of Solution
The mass of liquid water and steam is the same that is 1 g at
Therefore, 1 g of steam at
