Density of a Regular Object
Aim: To determine the density of a regular solid(glass marble)
Apparatus:
Micrometer Screw Gauge
Small Plastic Bottle
Electronic Beam Balance
1. Weigh the empty plastic bottle and record its mass as m1.
2. Place all 5 glass marbles into the plastic bottle and weigh again. Record the mass as m2.
3. Measure the diameter of one of the glass marbles from two different positions using the micrometer screw gauge. Record the diameter of the glass marble as d.
After finishing the experiment, we had to begin our calculations. We had to find the mass of one glass marble and record it as M.
To find the density of the glass marble, we had to take the glass marble's mass and divide it by its volume. Below is a link on how to find the volume of a sphere:
So why did we use 5 marbles instead of one?
To increase the accuracy of the result!
