WebMar 20, 2024 · Boiling chips or sticks ensure the boiling happens evenly, keeping things under control. The problem they solve is that, in a smooth vessel, there are often not many rough patches to initiate bubbles. Bubbles are much easier to initiate if there is a small rough patch on the vessel wall. Chips or sticks provide such a rough patch. WebActivity A: Vapor pressure and boiling point Get the Gizmo ready: Check that No solute is selected. Set the Air temp to 25 °C.
