Concept explainers
(a)
Interpretation:
Whether the particles in a gas are farther apart or closer together in comparison to the particles in a liquid should be determined and answer should be used for the explanation of following observation:
Liquids are less compressible than gases.
Concept Introduction:
The characteristics of gases and liquids are:
- Liquid has definite volume but indefinite shape whereas the gas has indefinite volume and shape.
- Liquid has more density in comparison to gas but less than solid.
- Liquid has small compressibility in comparison to gas but larger than solid.
- Liquid has small thermal expansion in comparison to gas (moderate) but larger than solid.
(b)
Interpretation:
The following observation should be explained.
The flow of gas is more freely in comparison to liquid.
Concept Introduction:
The characteristics of gases and liquids are:
- Liquid has definite volume but indefinite shape whereas the gas has indefinite volume and shape.
- Liquid has more density in comparison to gas but less than solid.
- Liquid has small compressibility in comparison to gas but larger than solid.
- Liquid has small thermal expansion in comparison to gas (moderate) but larger than solid.
(c)
Interpretation:
The following observation should be explained.
All gaseous mixtures are solutions after stirring.
Concept Introduction:
The characteristics of gases and liquids are:
- Liquid has definite volume but indefinite shape whereas the gas has indefinite volume and shape.
- Liquid has more density in comparison to gas but less than solid.
- Liquid has small compressibility in comparison to gas but larger than solid.
- Liquid has small thermal expansion in comparison to gas (moderate) but larger than solid.
(d)
Interpretation:
The following observation should be explained.
The density of substance in liquid state is higher than substance in gaseous state.
Concept Introduction:
The characteristics of gases and liquids are:
- Liquid has definite volume but indefinite shape whereas the gas has indefinite volume and shape.
- Liquid has more density in comparison to gas but less than solid.
- Liquid has small compressibility in comparison to gas but larger than solid.
- Liquid has small thermal expansion in comparison to gas (moderate) but larger than solid.
