What are the main properties of liquids (in contrast to gases and solids)? Check all that apply. Liquids have an indefinite shape and assume the shape of their container. Liquids have much higher densities in comparison to gases. Liquids are not easily compressed. Liquids have an indefinite shape and do not assume the shape of their container. Liquids are easily compressed. Liquids have not a definite volume. Liquids have a definite volume. Liquids have lower densities in comparison to gases.
