Vapor Pressure and Heat of Vaporization Introduction: Evaporation is the process of a liquid becoming vaporized. When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid‚ new gas molecules exerts pressure in the sealed container‚ while some of the gas condenses back to the liquid state. If the temperature inside

The Effect of Exercise on Blood Pressure Katie Law-Balding June 28‚ 2010 Abstract The purpose of this experiment was to see what effect 30 seconds of physical activity would have on a subject’s blood pressure. In this case‚ physical activity is defined as stair running at a moderate pace for 30 seconds. Standing blood pressure was measured before and after physical activity for comparison purposes. Three trials were completed and initial blood pressure was 94/75 mmHg‚ 125/92 mmHg‚ and 106/92

Chapter 3 Pressure Measurement Examples Example 3.3 A special high pressure U tube manometer is constructed to measure pressure differential in air at 13.8 MPa and 20oC. When an oil having a specific gravity of 0.83 is used as the fluid‚ calculate the differential pressure in N/m2 that would be indicated by a 135 mm reading. p − pa = m g h( gc m − f ) = (0.83)(1000) = 830kg/m 3 = = p 13.8 × 10 6 = f a RT (287)(293) g h( m − f ) p − pa = gc = 9.81(0.135)(830 − 164.11) = 881.51N/m 2 Example

of the pressures teens face‚ the stress they go through on a daily basis‚ and the constant want and need to fit in and be liked by their peers. But aside from all of those issues‚ one of the biggest challenges that teens face every day is peer pressure. Teens are often influenced to do things by their peers because it’s a person’s tendency to go along with the crowd. Although there is both positive and negative peer pressure‚ teens are more likely to give into the negative peer pressure such as

chemical‚ acoustic or thermal energy. While the term transducer commonly implies the use of a sensor/detector‚ any device which converts energy can be considered a transducer. Transducers are widely used in measuring instruments. A sensor is used to detect a parameter in one form and report it in another form of energy‚ often an electrical signal. For example‚ a pressure sensor might detect pressure (a mechanical form of energy) and convert it to electricity for display at a remote gauge. An actuator

Some parents are at their children’s back daily pushing them to excel academically. Nothing less than As would please them. Parental pressures to pursue academic success have both positive and negative effects on their children. Some children need parental pressure to study. They have not realised the value of academic achievements. This is especially true for children who are late bloomers. Still carefree about life‚ they prefer to indulge in their favourite sports‚ television programmer and other

Vapor Pressure and Enthalpy of Vaporization of Water 1/9/12 Emily Toy Lab Partner: Zack Ronnei Instructor: Ms. Olsen‚ AP Chemistry Purpose: The purpose of this lab is to find the vapor pressure of water at temperatures between 50oC and 80oC. Procedure: 1. Take a10 mL graduated cylinder and fill it with 7 mL of water. 2. Next fill a 1000 mL beaker ¾ full with water. 3. Cover the graduated cylinder by putting your finger on top and place the cylinder in the 1000 mL beaker. Make

Due to the rise in demand for wireless sensor networks in recent times‚ significant shift is observed from traditional‚ wired technologies to upcoming wireless technologies. Asia-Pacific is expected to grow at the highest rate due to increase in production activities in APAC‚ huge population base‚ and lucrative government policies. China is‚ in fact‚ the growth engine for automation in Asia-Pacific; in spite of lower levels of plant automation. India is also gaining market shares worldwide.The WSN
