Part 2: Water Drop Shapes 1. Obtain a clean plate and a square of wax paper. Fill a glass of water. 2. Dip a clean finger in the water and then carefully drop one drop onto the plate. 3. Repeat Step 2 with the wax paper. 4. Carefully examine and describe the drop shapes. 5. Explain the difference in drop shape in terms of functional groups, adhesio (the formation of hydrogen bonds between molecules of different types) and hydrophobic interactions. You may do this later when you're completing yo write-up. 6. Research an organism that uses this property of water. Then, explain how the structure of water makes it possible for the organism to use water in this way.
Kinetic Theory of Gas
The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all directions. It also says that the constituent particles/molecules undergo elastic collision, which means that the total kinetic energy remains constant before and after the collision. The average kinetic energy of the particles also determines the pressure of the gas.
P-V Diagram
A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and volume (V) corresponding to the thermodynamic system under study. The P-V diagram is used as an indicator diagram to control the given thermodynamic system.
