Question

Explain the fluidity of liquids in relevance to the postulates of the kinetic molecular theory.

PROCEDURES A. Surface tension 1. Place 3 5-peso coms on a flat surface. 2. Drop by drop; fill in the coin surfaces with water. Count how many drops of water one coim can contain without spilling the water on the edge of the coin. Stop counting once the water spills. 3. Wash the coin and wipe dry. Repeat the process using baby oil, cooking oil and rubbing alcohol in place of water. 4. Tabulate your data. B. Polarity 1. Put 10ml (2 tsp) of acetone in a plastic cup. 2. Add the glitters and stir until the color of the glitters is dissolved in the acetone. 3. In another plastic cup, put 5 ml (1 tsp) water and add food coloring. 4. Slowly decant the mixture of acetone and glitters into the cup containing food coloring. 5. Shake the mixture and note what happens. 6. Repeat steps 1, 2 and 3. 7. Add about 20 grams (4tsp) salt into the water containing food coloring. 8. Slowly decant the mixture of acetone and glitters into the cup containing water, food coloring and salt. 9. Describe the difference of the two set-ups. 10. Record all your observations. C. Movement of particles 1. Fill in one small plastic cup with hot water. 2. Add 1-2 drops of red food coloring. 3. Fill in another plastic cup with cold water. 4. Add 1-2 drops of blue food coloring 5. Partially submerge the two cups in a plastic fill ed with tap water. | 6. Prick a hole at the bottom of the two plastic cups. Observe and record the direction and speed of movements
