How will you determine the density of a stone using a measuring jar?

Answer variants:

Take the volume as

$V_{1}$

Thread should not touch the cylinder walls

Note the readings of the measuring cylinder

Mark the volume as

$V_{2}$

Now, the level of water is increased

Measuring cylinder is filled with water

Tie a stone piece of thread and immerse into the water

The density of a small irregular piece of stone can be found by .

Procedure:

STEP 1:

STEP 2:

STEP 3:

STEP 4:

STEP 5:

STEP 6:

STEP 7:

Inference:

The stone occupied the space inside the cylinder by some amount of water. This made the water level to .

The volume of water displaced will be occupied by the stone in the container. This technique was found by .

Formula:

$Volume of stone = i_{i} - i_{i}$
