Interpretation:
To find out the state of matter that is compressible.
Concept Introduction:
Anything that has mass, volume and occupies space is known as matter. There are three
Answer to Problem 1SAQ
Correct answer:
Option (a) −Gas.
Explanation of Solution
Reasons for the correct statement:
Option (a):
Gas: In this state of matter, the intermolecular forces are very weak due to which the particles (atoms, ions, or molecules) are widely separated and remain in rapid motions. Thus, gases are compressible and have no definite volume and shape.
Reasons for the incorrect statements:
Option (b):
Liquid: In this state of matter, the intermolecular forces are strong but less than in solids due to which the particles (atoms, ions, or molecules) are loosely connected and can move past each other. Thus, liquids are incompressible and has definite volume and but not definite shape (take the shape of container).
Option (c):
Solid: In this state of matter, the intermolecular forces are very strong due to which the particles (atoms, ions, or molecules) are closely-packed and cannot move randomly. Thus, a solid are rigid, incompressible and has high mechanical strength and has definite shape and volume.
Option (d): Therefore the correct answer is option (a). None of the above option is not applicable for any option.

- Indicate whether each of the following statements about the physical states of matter is true or false. a. The term indefinite shape applies to both liquids and gases. b. Thermal expansion for a gas is generally less than that of the corresponding liquid. c. The compressibility of a liquid is generally greater than that of the corresponding solid. d. The density of a liquid is about the same as that of the corresponding gas.arrow_forwardClassify each of the following statements as true or false. a Intermolecular attractions are stronger in liquids than in gases. b Substances with weak intermolecular attractions generally have low vapor pressures. c Liquids with high molar heats of vaporization usually are more viscous than liquids with low molar heats of vaporization. d A substance with a relatively high surface tension usually has a very low boiling point. e All other things being equal, hydrogen bonds are weaker than induced dipole or dipole forces. f Induced dipole forces become very strong between large molecules. g Other things being equal, nonpolar molecules have stronger intermolecular attractions than polar molecules. h The essential feature of a dynamic equilibrium is that the rates of opposing changes are equal. i Equilibrium vapor pressure depends on the concentration of a vapor above its own liquid. j The heat of vaporization is equal to the heat of fusion, but with opposite sign. k The boiling point of a liquid is a fixed property of the liquid. l If you break shatter an amorphous solid, it will break in straight lines, but if you break a crystalline solid, it will break in curved lines. m Ionic crystals are seldom soluble in water. n Molecular crystals are nearly always soluble in water. o The numerical value of heat of vaporization is always larger than the numerical value of heat of condensation. p The units of heat of fusion are kJ/gC. q The temperature of water drops while it is freezing. r Specific heat is conerned with a change in temperature.arrow_forwardIdentify two common observations indicating some liquids have sufficient vapor pressures to noticeably evaporate?arrow_forward
