is commonly used in chemistry when compounds need to be seperated because of their differences in their boiling points. Many organic compounds are volatile. Meaning they have high vapor pressures and low boiling points. During distillation‚ volatile compounds are heated to a boiling in container known as a pot. The vapors produced are colled and reliquefied by passing them through a water cooled condenser. They are then collected in seperated container called the receiver. This technique is used to

subtitle discusses the theories that the researchers will be supporting which is directly relevant to the research. 2.1.1 Theory of Relative Humidity Relative humidity is the relationship between the actual water vapor pressure and the maximum possible water vapor pressure. As stated by PAGASA (Philippine Atmospheric‚ Geophysical and Astronomical Services Administration) “Due to high temperature and the surrounding bodies of water‚ the Philippines have a high relative humidity. The average

water molecules was vaporizing at any time during the distillation. Even though the components of spearmint oil have low vapor pressure‚ they are volatile enough to vaporize to some extent and a small amount will lifted off with the water molecules. This boiling will occur when the independent internal vapor pressures are equal to 760 torr‚ which is the external vapor pressure. It is noted that steam distillation‚ unlike regular distillation‚ it does not follow Raoult’s Law. After steam distillation

Peer pressure is not bad thing. We all are influenced by our peers‚ both negatively and positively. It helps define who we are and how we feel about subjects in our lives. It is how we chose to react to peer pressure that defines who we are as an individual. Are we a leader or a follower? Both types of people are needed to make the world go around. ’A healthy part of every child’s development is involvement with their peers. This is especially true during adolescence as teenagers develop a sense

Effectiveness of Negative Pressure Therapy on Wounds Heather Downey ECPI University Effectiveness of Negative Pressure Therapy on Wounds Negative Pressure Therapy (NPT) is a non-invasive treatment using negative pressure to treat open wounds with the assistance of foam or gauze as the wound filler (Lee‚ 2011‚ p. 114). NPT also goes by the name Negative Pressure Wound Therapy (NPWT)‚ Topical Negative Pressure (TNP)‚ and Vacuum Assisted Closer (VAC). According to Thompson (2008)‚ NPT can be

‘Low pressure atmospheric systems have more of a short term impact than high pressure systems.’ Discuss. Low pressure atmospheric systems are also known as depressions or cyclones and they form in mid- and high-latitudes. They are formed by the mixing of cold and warm air‚ the warm air is lighter‚ so it rises above the denser‚ cold air and forms a centre of low pressure. High pressure atmospheric systems are also known as anticyclones and have very different characteristics to depressions. Anticyclones

The Negative Effects of Peer Pressure in the Teenaged Years He’s in the store‚ there’s ten dollars on the counter and the cashier isn’t paying attention. His obnoxious friend yells "Do it!!!!" Then you’re facing a battle in your mind whether you should or not. He start sweating‚ and he sees his friend getting frustrated as he says‚ "Come on…bitching out?" He feels stuck. Instead of doing what he know is right‚ he slowly reach out his hand and steals. Ever experienced a similar situation? If so

Peer pressure is defined as the social influence a peer group exerts on its individual members‚ as each member attempts to conform to the expectations of the group. No matter the generation‚ peer pressure plays a big role throughout people’s lives. Whether it starts with how people dress or who they hang out with‚ peer pressure is virtually everywhere. People may think that they are not affected by peer pressure‚ but every choice they make is centered on the opinions of others. Peer pressure can get
