Indicate whether each of the following statements about the physical
- a. The term “definite volume” applies to both solids and liquids.
- b. Thermal expansion for a liquid is generally greater than that of the corresponding solid.
- c. The compressibility of a gas is generally less than that of the corresponding liquid.
- d. The density of a solid is about the same as that of the corresponding gas.
Interpretation:
Whether each of the given statements about the physical states of matter is true of false has to be indicated.
Answer to Problem 7.1EP
From the given statements the correct options are (a) and (b).
Explanation of Solution
Reason for correct option:
Solids have a definite shape and volume due to individual particles in a solid have fixed positions with respect to each other why because they don’t have considerable amount of thermal energy to overcome the intermolecular interactions between them. Similarly, individual particles in a liquid can move freely each other and liquid has definite volume but no shape and shape can be considered by its container shape. Hence, the statement of option (a) the term definite volume applies to both solids and liquids. So, option (a) is true. Thermal expansion for a liquid is generally greater than that of the corresponding solid. Hence, the statement of option (b) is true.
Therefore, among the given statements, correct options are (a) and (b).
Reason for incorrect options:
The compressibility of gas is greater than that of corresponding liquid because particles in gas are freer and are in random direction and has no definite volume and liquids has definite volume and when an external force is applied to both the compressibility of gas is more than liquid. Hence, the statement of option (c) is false. The density of a solid is more than that corresponding gas. Hence, the statement of option (d) is false.
Therefore, among the given statements, incorrect options are option (c) and (d).
