- A sample is a kind of matter
- A sample in a cylindrical container has a cylindrical shape and a fixed volume
- Therefore, the matter has the same shape as the container and fixed volume

- The matter has the same shape as the container and fixed volume
- Matter with variable shape changes shape in different container
- So, the matter may have a variable shape and a fixed volume

- The matter has the same shape as the container and fixed volume
- Hence, the matter may have a fixed shape and a fixed volume

- The matter may have a variable shape and a fixed volume
- The matter may have a fixed shape and a fixed volume
- So, the matter may have a fixed or variable shape and fixed volume

- Matter in the solid phase has definite volume
- Matter in the solid phase has definite shape
- Hence, matter in solid phase has definite volume and definite shape

- Matter in the liquid phase has definite volume
- Matter in the liquid phase has variable shape
- Therefore, matter in the liquid phase has a variable shape and definite volume

- The matter may have a fixed or variable shape and fixed volume
- Matter in solid phase has definite volume and definite shape
- Matter in the liquid phase has a variable shape and definite volume
- So, the matter may be in solid phase or in liquid phase

Therefore, the matter may be in solid phase or in liquid phase
