Density  Of  Oil.

Name of the Student:  

Introduction:

               The density of any given substance is the mass per unit volume. The density of oil is the mass of oil present per unit volume.

               The density of a particular material does not change with change in gravity as there is no change in mass of the material or the volume.

   The density of oil= [pic 1]

       The units of density are g/ml (gram per millilitre)

 Research Question:

 How does mass of oil depend on volume of the oil taken ?

Hypothesis:

From the formula it can be predicted that the mass of oil is directly proportional to the volume of oil

Mass of oil ∞ volume of oil.

Variables:

Independent variable: volume of the oil taken in the measuring cylinder measured in ml - V

Dependent variable: mass of the oil measured in gram - M 

Controlled variable(s): Temperature=34C    

                                           Pressure:1 atm

                                           Material of oil: castor oil

Procedure:

  • Take a glass measuring cylinder of 10ml capacity.
  • First weigh the empty cylinder and note down the reading.
  • And pour 1 ml of castor oil into the jar and measure the weight.
  • It should be ensured that the upper meniscus of the oil in the cylinder touches the measurement mark.
  • Then add 1ml and take the reading once again.
  • go-on adding  get 6-8 readings.
  • 8 readings are taken because the cylinder is of 10ml capacity.
  • Now subtract the weight of empty cylinder from all the readings taken.
  • Divide the mass with volume.

Raw data:

  • Mass of the measuring Cylinder = mo= 7.69 g.

S.No

      volume of the oil

       (V±0.25) ml

mass of the cylinder + oil   (m ± 0.001 )g

mass of the oil= M

=[(m - mo)±0.002]g

K=density = mass/volume

                   = M/V g / ml
