Experiment:
Now, let’s explore how density works with mass and volume in everyday stuff.
Let’s Explore the concept through an interesting experiment.
Saad took a wooden log and with the help of a carpenter made t different objects from the log that is :
A door,
a wooden cube
a wooden box.
His team is curious to know the difference in their Density as all three objects have different mass and volume and to determine the density of the objects, they start their experiment.
Objective of the experiment:
To calculate the density of wooden objects.
Apparatus:
Electronic Balance,measuring tape, calculator and a notebook.
Procedure:
They measure the mass of all three objects(one at a time), by placing the objects on electronic balance and recording them in the observation table.
Then they used measuring tape to measure their length,breadth and height to calculate volume through a formula that is V= l x b x h
Observation Table:
Objects | mass(g) | length(cm) | breadth | height | v=lxbxh cm3 | density=m/v g/cm3 |
door | 8000 | 20 | 20 | 10 | 4000 | 2 |
cube | 800 | 20 | 20 | 1 | 400 | 2 |
box | 80 | 10 | 2 | 2 | 40 | 2 |
Results:
The density of all three objects is the same, as they all are made from the same type of raw material.
Conclusion:
It shows that irrespective of how big or small the object is, or how heavy or lighter it is, Density only measures the mass present in the unit volume of that given object.
