Liquids do not have a definite shape but have a definite volume, taking the shape of the container they are in.
The molecules of liquids are in constant motion, leading to evaporation and diffusion. The densities of liquids
are higher than gases but similar to solids, with negligible spaces between molecules.
Liquids have intermediate intermolecular attractive forces between gases and solids, affecting their melting and
boiling points. They can be converted into solids by decreasing their kinetic energy through cooling. Unlike
gases, liquids do not show a significant increase in volume when heated.
What is the general shape of liquids?
Liquids don’t have a definite shape but have a definite volume. They adopt the shape of the container they are in.
What kind of motion do molecules of liquids possess?
Molecules of liquids are in a constant state of motion, leading to evaporation and diffusion.
What are the intermolecular attractive forces like in liquids?
The intermolecular attractive forces in liquids are intermediate between gases and solids, affecting their melting and boiling points.
Can liquids be converted into solids by cooling?
Yes, liquids can be converted into solids on cooling by decreasing their kinetic energy.
