Bill Nye: Phases of Matter Questions
and Answers | 2024/2025 | 100% Pass
How does a solid maintain its shape?
✔✔A solid maintains its shape because its particles are closely packed and vibrate in place.
What happens to the particles in a liquid?
✔✔In a liquid, particles are close together but can slide past one another, allowing the liquid to
flow.
What is the state of matter with the most energy?
✔✔The state of matter with the most energy is gas, where particles are far apart and move freely.
What causes ice to melt into water?
✔✔Ice melts into water when heat energy is added, causing its particles to gain energy and move
more freely.
What is vaporization?
1
, ✔✔Vaporization is the process where a liquid turns into a gas, usually through boiling or
evaporation.
What is the difference between evaporation and boiling?
✔✔Evaporation occurs at the surface of a liquid at any temperature, while boiling occurs
throughout the liquid at a specific temperature.
What happens to gas particles when they cool down?
✔✔When gas particles cool down, they lose energy, slow down, and may condense into a liquid.
How does pressure affect the state of matter?
✔✔Increasing pressure can force gas particles closer together, potentially turning them into a
liquid.
What is condensation?
✔✔Condensation is the process where gas turns into a liquid as it cools down and loses energy.
What occurs during the process of sublimation?
