Gertrude is observing liquids at a birthday party. Some are sweet, some are hot, and some are sticky. If she could look at the particles of the liquids, which statement would be true?
The particles are far apart and moving fast, with no shape.
The particles may touch but they can flow past each other.
The particles are in close contact and cannot move from their places.
The particles have no arrangement.
Herbie notices that a spill on the kitchen floor was gone the next morning. The best description of what happened to the spill is
It evaporated
It sublimated.
It boiled.
It froze.
How are boiling and evaporating different?
They both are processes that change a liquid to a gas.
Boiling requires heat to be added so the particles rapidly change to a gas.
