No. They can be heated or cooled.
Yes
Yes
They are both incompressible, and they have a fixed volume at a fixed temperature.
No, liquids do not have a fixed volume - their volume is that of the container
liquids are Not rigid in shape, but DO have a fixed volume
They have no fixed shape. They don't have a definite volume, the volume depends on temperature and pressure.PV=nRT
Any substance which is liquid at that temperature. Liquids evaporate at any temperature. If you mean boiling, which happens at a fixed temperature at fixed pressure, then nitric acid fits.
solids and liquids
Yes they do. Liquids have no fixed shape and gases have no fixed volume.
Solids and liquids both have fixed volumes.
All liquids have a fixed volume and takes the shape of its Container.
Liquids meet these requirements.
