## Introduction

In this experiment, we will determine different factors affecting adhesion In Liquid and whether it is possible or not for different shapes to affect adhesion. We will also determine if the adhesion is affected by the amount of area, type of liquid, depth of liquid, and temperature.

## Aim

To determine the effect of shape, area, and temperature, on adhesion.

## Theory

1. When two substances come in contact, adhesion occurs.

2. Adhesion occurs for those substances also meet a little with each other.

## Requirements

1. Four Shapes (circle, hexagon, triangle, and squares) of three different sizes

2. Simple Balance Beam

3. Gram Weight

4. Water

6. Motor Oil

7. Notebook

8. Plexi-Glass

## Procedure

Step 1: Construct a simple balance beam.

Step 2: Hang the shapes (circle, triangle, square, and hexagon) on this beam.

Step 3: Use a gram weight to counterbalance the adhesion between the liquid and the plexiglass shape. Here, the liquid will be rubbing alcohol, water, and motor oil.

Step 4: Now, test the shapes at one quart and two quarts depth.

Step 5: For performing temperature tests, use boiling and cold water.

Step 6: Test each shape to find how much force is needed to detach this shape from the surface of the liquid.

Step 7: Repeat this experiment three more times.

## Observation

1. We observed that the more sides a shape has, the more its adhesion is, except for the hexagon, which has six sides, but it performed poorly.

2. Bad performance of hexagons may be because of poorly cut sides and less area.

3. We find that the denser the liquid, the better the adhesion. And that’s why water had better adhesion among the three because of its density.

4. The more area confirms, the better adhesion.

5. The adhesion works better for cold substances.

6. Depth did not affect the adhesion as the distance between them was minuscule.

## Result

1. Circle was the better shape for adhesion among the four.

2. Water was the best liquid for adhesion.

3. The largest size among all performed the best. This means that the larger size had better adhesion.

4. The cooler the liquid, the better the adhesion.

5. And, for depth, two quarts had better adhesion than one quart.

## Conclusion

In this experiment, we determined different factors affecting adhesion In Liquid, like kind of shape, size, temperature, liquid, and depth.

Q.1 What was the aim of your experiment?

ANS. We aimed to determine the effect of shape, area, and temperature, on adhesion.

Q.2 What was the effect of shape on adhesion?

ANS. The Circle was the better shape for adhesion among the triangle, hexagon, circle, and square.

Q.3 What is the role of sides in determining the effect of shape on adhesion?

ANS. The more side a shape has, the more its adhesion.

Q.4 Why is hexagon an exception?

ANS. The bad performance of the hexagon may be because of poorly cut sides and less area.

Q.5 What is the effect of area on adhesion?

ANS. The more the area, the better the adhesion.

Q.6 What is the effect of temperature on adhesion?

ANS. The more the temperature, the lesser its adhesion will be.

Q.7 What is the effect of density on adhesion?

ANS. The greater the density, the better the adhesion.

Q.8 What is the effect of size on adhesion?

ANS. The larger the size, the better the adhesion.
