Summary: Experiment 9 is conducted to identify the importance of intermolecular forces and how they affect molecules. Intermolecular forces are forces between molecules that determine whether the molecule is a solid‚ liquid‚ or gas under standard conditions. In our lab‚ we measured the maximum and minimum temperature reached and time it took to reach it of alcohols and alkanes. In addition‚ we measured the vapor pressure of the liquid at different temperatures. Through Experiment 9‚ we concluded

so angry that he had flames burning all off of him. At the beginning Flame got put in a dilemma because he had a choice to either cheat or play the board game the right way. When he was in the air and he woke up he was in a muddle and did not know what was happening in the moment and he was terrified at the time. Zeus and Frost were now counting the board game and acting like nothing happened. As they were playing the game they realized that Flame was so opinionated and each time somebody cheats

to government officials and the use of their power and force. These areas can easily be misconstrued and misunderstood. Police officers are put in situations where they are sanctioned to use mental and physical force to catch criminals with the goal of solving a crime. (p481). When it comes to police force‚ some have a good understanding of its purpose and feel that it is needed. Others believe that with training and self-control‚ police force could be minimized. We live in a society that is unpredictable

At the onset of the American Revolution‚ the sociology and agenda of the patriotic elite seemed to mirror that of the people. Many influential figures in the colonies‚ as well as most of the common people‚ had had enough of what they viewed as British tyrannical rule encroaching on their lifestyles. Visionaries such as Benjamin Franklin and Thomas Jefferson dreamed of a self-governed country founded on a basis of equality and liberty. Of course‚ these fundamental rights weren’t intended for everyone

Matt Ennis 10/3/10 The Use of Force A physician is summoned to make a housecall on a family with who he has had no prior contact. He quickly sizes up the situation: the household is poor but clean; the patient is a female child whose parents are nervously concerned‚ dependent on‚ yet skeptical of the doctor. The child ’s beauty and piercing stare make an immediate impression on him. Concerned that diphtheria may be the cause of illness‚ he uses his customary professional manner

The Lower Canada rebellions that took place in 1837 and 1838 had complicated roots. It would be an over simplification to state that the differences were just between the governor and the assembly or only political. The rapidly growing population had many facets that caused rifts between itself and the ruling government in place. Social differences‚ economic opportunity‚ and political perspectives all had roles to play in creating a climate that led to open armed rebellions. These differences led

Intermolecular forces exist between independent particles‚ such as atoms‚ ions‚ or molecules. They can be forces of either attraction or repulsion. The amount of charge‚ how it is distributed‚ and the length of time that a charge distribution exists can affect the strength of intermolecular forces. And despite having variable force strengths‚ all intermolecular forces are considered weak compared to chemical bonds‚ or intramolecular forces. Chemical bonds are not only stronger; they are also more

[pic] The product of average force and the time it is exerted is called the impulse of force. From Newton’s second law [pic] the impulse of force can be extracted and found to be equal to the change in momentum of an object provided the mass is constant: |[pic] |Calculation | The main utility of the concept is in the study of the average impact force during collisions. For collisions‚ the mass and change in velocity are often

HYDROSTATIC FORCE (EXPERIMENT 1) INTRODUCTION The determination of force which are exerted by liquid which are at rest on surface immersed in liquids. From the study by hydrostatic‚ the following principles have been established : a) There are no shear stress present when the fluid is not in motion. b) The pressure exerted by a fluid under hydrostatic conditions. This pressure acts perpendicular to an immersed surface. c) Hydrostatic pressure various linearly‚ increasing with an

Centripetal force (from Latin centrum "center" and petere "to seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre
