Q: Which of the following is / are true? A. Rigidity : (Toughness) According to the type of substance, size varies depending on the location of the particles. For example, solids have a fixed size, while liquids attain the size of their vessel and if seen, gases have no shape. B. Compressibility : This is the quality of substances that reduces their volume at high pressure. This property is found in gases.
  • A. Both A and B are true.
  • B. Only A is true.
  • C. Only B is true.
  • D. Both A and B are false.
Correct Answer: Option C - Due to the properties of toughness in substances, the substance resists the shaking or bumps that hit on it before it breaks. Hence statement A is false and statement B is true, because the compressibility is found in most of the gases. Due to this properties their volume decreases at high pressure.
C. Due to the properties of toughness in substances, the substance resists the shaking or bumps that hit on it before it breaks. Hence statement A is false and statement B is true, because the compressibility is found in most of the gases. Due to this properties their volume decreases at high pressure.
