Lower Sec Science · Secondary 1 · Medium · Arrangement of particles
A student says: "Water boils at 100 °C because the water particles stop moving at this temperature." Using the particle model, how should this statement be corrected?
- At 100 °C, water particles move faster and can escape into the gas state
- At 100 °C, water particles slow down and become fixed in place
- At 100 °C, water particles stop moving and become heavier
- At 100 °C, water particles lose all energy and cannot move
