Explanation:
To Measure Internal Diameter And Depth Of A Given Beaker/CalorimeterUsing Vernier calipers And Hence Find Its Volume. Vernier caliper is ameasuring device that has two scales: the main scale and vernier scale such that the vernier scale slides over the main scale.

Explanation:
Determine and record the least count of the vernier caliper which is also known as the vernier constant.
To find the zero error, bring the movable jaw BD in contact with the fixed jaw AC. Repeat and record this three times. If there is no zero error, then record zero error as nil.
Now put the jaws C and D inside the beaker and open till they make contact with the inner wall of the beaker without any pressure. Tighten the screw without putting too much of pressure.
On the main scale, record the zero mark of the vernier scale. Just before the zero mark of the vernier scale, record the main scale reading which is known as main scale reading (M.S.R).
Let n be the number of the vernier scale division which coincides with the main scale division.
Rotate the vernier caliper 90° and repeat the steps 4 and 5 for measuring the internal diameter in perpendicular direction.
To measure the depth, find the total reading and zero correction.
The edge of the main scale of vernier caliper should be placed on the peripheral edge. Care should be taken so as to make the strip go freely inside the beaker along its depth.
Once the moving jaw of the vernier caliper touches the bottom of the beaker perpendicularly, the screw of the vernier caliper should be tightened.
For four different positions along the circumference of the beaker, repeat the steps 4 and 5.
Find the total reading and also zero correction.
For internal diameter, take two different mean values and for depth, take four different values.
Calculate the volume using proper formula and record the same in the result with units.
