SUBSTANCE EXPANSION
SIMPLE EXPERIMENT ON SUBSTANCE EXPENSION LIQUID AND SOLID SUBSTANCE

Activity 5.1

I.       Purpose                                 :

To find out the expansion of liquid

II.       Basic Theory                         :

              The train is a means of land transportation is relatively safe and comfortable and can carry passengers in large numbers. Trains run on rails. At the railroad connection there is a gap, Why should there be a gap? The slit width at night, while during the day become narrow because of exposure to sunlight.

              Most of the substance will expand when heated and shrink when cooled. When a substance is heated (the temperature is raised), then the molecules will vibrate faster and the amplitude of vibration will be greater, consequently the distance between the molecules of the object becomes larger and there was expansion. Expansion is increasing the size of objects due to temperature rise of the substance. Expansion can occur in solids, liquids, and gases.

III.       Materials and Equipments      :

·         Erlenmeyer flask

·         Water

·         Cooking oil

·         Alcohol

·         Capillary Pipe

·         Rubber Stoppers

IV.       Step Work                           :

1.     Heat the water, cooking oil, and alcohol in an Erlenmeyer flask with a pipe that was installed through a rubber stopper.

2.    Entering the third flask in boiling water

3.    Note the changes that occur

III.       Materials and Equipments      :

·           Musschenbroek

·           Aluminum

·           Copper

·           Iron

·           Burner methylated

IV.       Step Work                           :

1.     Arrange equipment so that the third position the needle indicates the same scale.

2.    Third Heat the rod a few minutes with the burner methylated, watch the needle of the third metal. What happened?
