Why do solids have fixed shape? The particles ______.
are too far apart
are very free to move
do not have enough energy to move out of position
can slide past each other but not move far enough to change shape
Which are the first particles to evaporate from a liquid? Those ____.
with the lowest average kinetic energy
with the highest average kinetic energy
closest to the surface of the liquid regardless of kinetic energy

Which of these statements best explain why a liquid's rate of evaporation increases when the liquid is heated?
The surface area of the liquid increases.
The average kinetic energy of the liquid decreases.
