The factors that would cause the lung to collapse are elastic recoil and high surface tension. And the factors that prevent the lungs from collapse are negative intrapulmonary pressure and surfactant. During expiration : volume increase and pressure decrease During inspiration : volume decrease and pressure increase The role of surfactant is to decrease surface tension by more than 40 times. And it’s effect on surface tension is to prevent them from PO2 in alveolar : 104 PO2 in venous blood

Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between the molecules

In this paper‚ we are going to look at Tampa-St. Petersburg-Clearwater Metropolitan Statistical Area (MSA)‚ which is defined by the United States Census Bureau. This MSA is also be called as Tampa Bay Area. It is a region close to Tampa Bay and west of central Florida. Throughout this paper‚ I will collect data from different categories of the Tampa MSA and going to mainly focus on these areas: population and population growth‚ population density‚ race & ethnicity‚ immigration‚ education attainment

Area 51 Area 51 is a nickname for a military base that is located in the southern portion of Nevada in the western United States (83 miles north-northwest of downtown Las Vegas). Situated at its center‚ on the southern shore of Groom Lake‚ is a large secretive military airfield. The base’s primary purpose is to support development and testing of experimental aircraft and weapons systems. Its secretive nature and undoubted connection to classified aircraft research‚ together with reports of
