select the true statement.
changes in volume and pressure affect solids.
changes in volume and pressure affect all physical states.
changes in volume and pressure affect gases.
changes in volume and pressure affect liquids.
solid
rigid
fixed shape
fixed volume
liquid
not rigid
no fixed shape
fixed volume
gas
not rigid
no fixed shape
no fixed volume

Explanation:

• Solids have a fixed shape and volume. Changes in volume and pressure do not easily affect solids as the particles are closely packed and have strong intermolecular forces.
• Liquids have a fixed volume but no fixed shape. While they are more compressible than solids, they are not as affected by changes in volume and pressure as gases.
• Gases have no fixed shape or volume. They are highly compressible. According to gas laws (e.g., Boyle's law \(P_1V_1 = P_2V_2\) for a fixed amount of gas at constant temperature), changes in volume and pressure have a significant impact on gases.

Answer:

Changes in volume and pressure affect gases.
