Density :
Mass/volume = density
to find density of irregular :
1.weigh the irregular solid to find its mass(M)
2. fill the measuring cylinder 1/3 with water(V1)
3. tie a string to the irregular solid and lower it into the water(V2)
Note : use a sinker if irregular solid floats
4. The volume of the irregular solid is (V1 - V2)
5. Take the mass and divide by the volume to find the density of the irregular solid.
Kinetic particle theory
so in this experiment:
The "bright spots" move in random motion because they collide with the air and wate molecules.
As the temperature increases the molecules would start to vibrate and move faster.
KPT< this website helps to explain what kinetic particle all about.
Here is the Theory
1. All matter is composed of tiny particles
2.These particles are in constant motion
3.The amount of motion is proportional to the temperature
4.Solid, liquid and gas differ in the freedom of the motion of their particles and the extent which the particles interacts
