Internal Assessment: Rate of Evaporation Ann George Mr. Frias/4th Period Wheeler High School Research Question How will changing the molar mass of alcohol affect the rate of evaporation‚ represented by the change in temperature over time‚ measured using a temperature probe? Research/Abstract Alcohol is an organic compound in which the hydroxyl functional group‚ OH‚ is bound to a carbon atom. Its carbon center should be saturated; it should have single bonds to three other atoms. The different types

Determination of Rate and Order of a Reaction Results This experiment used a spectrometer to find the wavelength with maximum absorbance in a green food coloring solution. For this particular solution the wavelength was 629.7 nm. The system was then calibrated to that and was set to measure the food coloring and bleach solution. The measured visible light absorbance of the mixed solution was collected over a time of 200 seconds and eight points were then selected and placed into the Absorbance

1. How does Teletech Corporation currently use the hurdle rate? Teletech Corporation currently uses a single hurdle rate for both of their divisions. The divisions are Telecommunications Services and Products and Services. They use the hurdle rate based on the cost of capital which is a rough estimate of the Teletech’s WACC. They calculate it at 9.3% based on the cost of capital‚ beta‚ and WACC. 2. Please estimate the segments WACCs for Teletech (see worksheet Exhibit 1). As you do this

Madeleine Socio 125 T8 Nov 20‚ 2012 Teen Birth Rates in the United States Sociological imagination is a concept introduced by C. Wright Mills that allows us the ability to “think ourselves away” from familiar routines in our daily life. It also shows us a “vivid awareness of the relationships between experience and wider society”. An example of this concept is how the changing sexual norms in our society have influenced the issue of high teen birth rates in the US. Sexual behavior among teens has changed

Chapter 14 - Base Rate Base rate is the mean number of times an event occurs divided by the mean number of times it might occur. Representativeness is a bias when people wholly and exclusively rely on pre-conceived notions. Empirical evidence suggests that people formulate their judgments by relying on representativeness and neglect the base rate. This results in sub-optimal judgments and guesses. Given a plausible base rate‚ the anchoring of judgment of the probability of an outcome whilst putting

Activity One: 1. The two major variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over

reverse repo rate These are the rates which are used by reserve banks (RBI in India) to inject or absorb liquidity from banking system. Repo rate is the rate at which the RBI lends money to the commercial banks or the rate it which banks borrow money from RBI. When RBI increases repo rate borrowing from RBI becomes more expensive. RBI increases repo rate to make it more expensive for the banks to borrow money. If RBI reduces the repo rate means banks can borrow money at cheaper rates. The term repo

Introduction: Basal Metabolic Rate has been defined as the minimum amount of energy needed by an animal to maintain the basic functions of survival (such as breathing). Several factors including age‚ gender‚ weight‚ and exercise affect the BMR. "BMR increases with increasing muscle tissue" therefore‚ exercising will enhance BMR while with increasing age‚ BMR is reduced (Scott‚ 2008). Also gender differences exist between males and females; it has been shown that males have higher BMRs
