Tires are round-shape object surrounded with wheels that are made of metal connected with axle of cars so that car’s tires don’t wear
Because tires reach ground for driving and support car’s weight, It plays a role like man’ shoes
Therefore we need to concern considerably and manage tires cotinuously
Tires conduct the following four important function
First, Function of conveying driv

Objective
Purpose of this experiment
Understand the colligative propertise and determine the molecular weight of the unknown material based on freezing-point depression
(중략)
Discussion
Theoretically, the freezing point of this should be the horizontal line, while the others should have some inclination.
However in this experiment, there are several temperatures which w
Polymer density can be determined by
measuring the volume and weight of
polymer.
Two different methods are used;
(1) Specific Gravity-Bottle Method
(2) Sink-and-Float Method
Measurement of Density
The mass is normally measured with an appropriate scale or balance.
The volume may be measured directly (from the geometry of the object) or by the displacement of a fluid.
