Procedure: Determine the correct weight of the empty graduated cylinder (measuring device). Fill up the cylinder(measuring device) with water, record the volume and weight of the cylinder with water. Do this for several trials, filling up the cylinder with water under different volumes. Using consistent units for weights and volumes corresponding to each trial, determine the trial densities as m/V in kg per cubic meter or gm per cubic centimeter.

Question

Procedure:

Determine the correct weight of the empty graduated cylinder (measuring device).

Fill up the cylinder(measuring device) with water, record the volume and weight of the cylinder with water.

Do this for several trials, filling up the cylinder with water under different volumes.

Using consistent units for weights and volumes corresponding to each trial, determine the trial densities as m/V in kg per cubic meter or gm per cubic centimeter.

Do another exercise by using other liquid,(cooking oil) like oil, kerosene, etc.

Tabulate the data and identify the liquid used.

Computation:

      Let V = volume of liquid ( or )

    = mass of empty cylinder (kg or gm)

    = mass of cylinder + liquid (kg or gm)

   m = mass of liquid (kg or gm)

   m =  mT-me

   p=m/V

Questions:

Will there be variation in density of water if there is temperature variation?

Why? _________________________
