Why is there a linear relationship between the mass added to a container and its displacement in water

[From: ] [author: ] [Date: 12-04-16] [Hit: ]
the volume of liquid displaced is equal to that of the volume of immersed object..cross-section area of container*rise in water level = mass added/density of solid..u know the cross-section area does not changes as well as density of a particular substance is fixed(so these will act as constants)........
I did a physics experiment, where mass was added to a Ziploc container and then its displacement was measured. I found that there was a linear relationship between these two variable but I need to explain why with laws, rules, and/or other physics equations. Thanks very much!

its easy..
according to archimedes' principle.. the volume of liquid displaced is equal to that of the volume of immersed object.. so
cross-section area of container*rise in water level = mass added/density of solid..

u know the cross-section area does not changes as well as density of a particular substance is fixed(so these will act as constants)..

hence,
rise in water level = k*mass added, which is a linear relation..
