Assertion: Liquids and gases are largely incompressible and densities are therefore, nearly constant at all pressures for liquid only.
Reason: Liquids exhibit a large variation in densities with pressure but gases do not.
Reason: Liquids exhibit a large variation in densities with pressure but gases do not.
View answer and explanation
Correct option: C
If assertion is true but reason is false
Option C (If assertion is true but reason is false) is correct because liquids are largely incompressible with nearly constant densities, while gases exhibit large density variations with pressure.
