Quick Q&A Before You Revise
Why do textbooks say particles attract each other?
Because matter can stay together only when there are forces pulling neighbouring particles toward one another. Stronger attraction gives solids more rigidity, while weaker attraction allows liquids and gases to move more freely.
How do I remember boiling versus evaporation?
Think of boiling as a fast bulk process that happens throughout the liquid at a fixed temperature, while evaporation is a slower surface process that can happen at ordinary temperatures.
Why do clothes dry slowly in the rainy season?
During the rainy season the air already contains a lot of water vapour, so humidity is high. Because of this, evaporation becomes slower and clothes take more time to dry.
