Lower Sec Science · Secondary 1 · Medium · Particle model of matter
A sealed syringe contains air. The plunger is pushed in so that the volume of air is halved while the temperature stays the same. According to the particle model, what happens to the spacing of the air particles?
- The particles become more closely packed as the volume decreases.
- The particles become larger to fill the smaller space.
- The particles move further apart from one another.
- The number of particles decreases to keep the spacing the same.
