Physic Lab 2: Liquid´s Density.

Practice #2

Material
-  Oil
-  Water
-  condensed milk

Procedure
We take our three liquids and weight each one in order to obtein the mass
With te cuantity of each sustance we obteined the volume of eaach liquid
We calculated the density if each substance
We saw the difference in density of the liquids and determined wich substance was the most dense and we tried to analize why?

Results & Images

 

Water
m=10g                                                p= m/V  =  10g/10cm3   = p=  1g/cm3
V=10ml=10cm2




Oil 
m=9g                                                  p= m/V  =  9g/10cm3  = p= 0.9g/cm3
V10ml=10cm3      




condensed milk
m=14.9g                                   p= m/V   =  14.9g/10.1cm3  =   p=1.47g/cm3
V=10.1ml=10.1cm3
                     



Physical Explanation

Density is defined like the number of molecules that certain substance has and certain molecules are more tightly packed than others and substance have varieties in the number of molecules, so that´s the reason why liquids are more dense than others.
