Use the postulates of the kinetic theory to explain the following: i)Matter can exist in three states ii)The pressure exerted by a confined gas decreases as its temperature is lowered iii)A gas of low molecular mass will diffuse through air faster than a gas of high molecular masseven though both are at same temperature. The Kinetic Theory can be used to describe the three physical states of matter namely‚ solid‚ liquid and gas. In this theory‚ some basic assumptions has to be made: a) all matter

Lab Report #1 Introduction A cell’s plasma membrane is known to be selectively permeable. This implies that the membrane is selective on what substances can pass in and out of the cell. There are two methods of transport that occur through the plasma membrane. One method of transport is called active process which uses ATP energy to transport substances through the membrane. The other method is called passive process which does not require the use of ATP energy. During passive processes

During the 1960s African Americans weren’t treated well and now they are treated as equals. They are valued better because of what Martin Luther King Jr did to help his race. People will act differently now if the Tom Robinson trial was happening now because people aren’t racist anymore‚ people will make up assumptions‚ and they have equal rights now. First and foremost‚ people would act differently because no one is really racist anymore and people have changed. For example‚ in the late 1960s

Critically Evaluate the Training of Mo Farah and Explain the Physiological Changes that will Occur. Mo Farah had to go through tough training to become the athlete he is today. Due to Mo’s type of events‚ (10‚000 and 5‚000 meters) he needs a high aerobic capacity and VO2 max. Aerobic capacity is how well the lungs‚ heart and the blood vessels work together‚ and VO2 Max is the maximum oxygen consumption attainable during maximal work. VO2 max can only be improved in 10 – 20% of the population

structure of something you didn’t even know existed‚ what you are imagining is James Watson. Watson changed molecular biology in amazing ways that changed science forever. He discovered the structure of DNA. James Watson had an extremely influential life. His main discovery was the structure of DNA‚ but he also discovered the helical construction of tobacco mosaic virus. The discovery of the molecular structure of DNA was a ginormous scientific breakthrough. Watsons current research includes the role of

CENTRAL DOGMA OF MOLECULAR BIOLOGY Molecular Biology Laboratory‚ Biological Sciences Department College of Science and computer Sciences‚ De La Salle University-Dasmarinas ABSTRACT: The central dogma of biology holds that genetic information normally flows from DNA to RNA to protein. In the experiment‚ DNA and RNA bead kits were used. Different coloured beads correspond to different nitrogenous bases‚ sugars and phosphates. Different structures of DNA and RNA were formed based on the sequences

Ms. Julie – Hysteria Background Information on Hysteria: Hysteria in the Victorian Era (Greek name uterus) was a medical condition that was diagnosed exclusively in women throughout the late 20th century. It was a “nervous illness” that interfered with the body and the mental state of women. There were a wide range of symptoms associated with Hysteria and it was found to be the second most common diagnosis of sickness in women in the Victoria Era. Women living during this time period were considered

Arnold Gesell. Although they stand at opposite poles‚ both have recorded facts useful to parents and professionals alike. This paper presents the highlights of their theories and focuses on their major differences. The views of Piaget and Gesell on how development occursIntroductionIn Psychology‚ very few theorists have impacted and influenced child development as did the work of Jean Piaget (1896-1980) and Arnold Gesell (1880-1961). Although they stand at opposite poles‚ both have recorded facts

In this essay‚ it will be discussed how the Kinetic Molecular Theory explains many gas law specifically Boyle’s gas law‚ Charles’ gas law‚ and Avogadro’s gas law. To understand what will be talked about is to first know what the Kinetic Molecular Theory is. In our textbook is says it is “A simple model for gases that predicts the behavior of most gases under many conditions.” First off‚ we will take a look at Boyle’s Law. As stated in our lab manual “at constant temperature the pressure which a given
