7. Standard density of water in English unit is 1000, 8. The standard unit of pressure in SI is kN 9. The gas constant of air in SI is equal to 0.287- kg-K
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.
i. answer 7 8 and 9
![General Directions: Read each questions and directions carefully and write your answers
and solutions in a clean sheet of paper. Show STEP BY STEP solution
and box your final answer. Noncompliance with the direction will
result to a wrong answer.
I. Write true if the statement is correct. if the statement is wrong, Write the word
or phrase that makes it incorrect and write the correct answer beside it. (ex:
meters → feet; Where "meters" is the incorrect word and "feet" is the
correct answer)
1. The acceleration due to gravity in SI unit is equal to 9.81
2. Acceleration is given by the derivative of the velocity with respect to time.
3. Velocity is given by the second derivative of the position of the particle with respect
to time.
4. When solving projectile motion problems, we analyze properties in the x and y
direction simultaneously.
5. The acceleration of a particle is given by the second derivative of its equation of
velocity.
6. Specific Weight is also called Relative Density.
