    Why can stones be piled up but not water?

    Solids have fixed shapes due to strong interparticle attractions.

    What happens to water when released from folded hands?

    It flows freely due to weak interparticle forces.

    How does air add weight to an inflated balloon?

    Air consists of particles that exert pressure inside the balloon.

    Is the air we breathe today the same as thousands of years ago?

    Air composition changes over time due to natural processes.

    What are constituent particles?

    They are the smallest units that make up a substance.

    What happens to sugar when dissolved in water?

    Sugar breaks into constituent particles that cannot be seen.

    What are interparticle spaces?

    They are gaps between particles that allow for movement.

    What decides the physical state of substances?

    The strength of interparticle attractions and distances between particles.

    How are particles held together in solids?

    Strong interparticle attractions keep them tightly packed.

    What occurs when solids are heated?

    Particles vibrate more and may transition to a liquid state.

    What is the melting point?

    The temperature at which a solid turns into a liquid.

    What is the melting point?

    It indicates the temperature at which a solid becomes a liquid.

    How do the particle arrangements differ in solids and liquids?

    Particles in liquids are farther apart than in solids.

    What happens to particles at the boiling point?

    They gain enough energy to escape into the gaseous state.

    What defines the shape of liquids?

    Liquids take the shape of their container due to free-moving particles.

    How do interparticle forces in liquids compare to solids?

    Interparticle forces in liquids are weaker than in solids.

    What is evaporation?

    It is the process of liquid turning into vapor at temperatures below boiling.

    What distinguishes gases from solids and liquids?

    Gases have no fixed shape or volume and fill their container.

    What happens to gas particles when compressed?

    They are forced closer together, reducing the space between them.

    What is the implication of liquids having a definite volume?

    Their volume remains constant regardless of the container shape.

    How does the behavior of water differ from gases when pressure is applied?

    Water is incompressible, while gas volume decreases under pressure.
