a sample is a kind of matter & a radium in a cylindrical conducts has a cylindrical size and a fixed want ->  the matter has the same shape as the container and fixed volume  the energy has the same size as the black and fixed want & matter with variable shape changes shape in different container -> the matter may have a variable shape and a fixed volume the matter may have a variable shape and a fixed volume  the matter has the same shape as the container and fixed volume -> the energy june have a fixed size and a fixed want the matter may have a fixed shape and a fixed volume  the matter may have a variable shape and a fixed volume & the energy june have a fixed size and a fixed want -> the matter may have a fixed or variable shape and fixed volume the matter may have a fixed or variable shape and fixed volume  matter in the solid phase has definite volume & energy in the mist causing has definite size -> matter in solid phase has definite volume and definite shape 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 -> energy in the steam mirror has a constant size and definite want matter in the liquid phase has a variable shape and definite volume  the matter may have a fixed or variable shape and fixed volume & energy in mist mother has definite want and definite size & matter in the liquid phase has a variable shape and definite volume -> the matter may be in solid phase or in liquid phase
