Correlation 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

“Whose nature?”. Cronon begins by remarking how people disagree about nature and how the main message in his book is that this argument is inevitable. He says‚ “Nature becomes our dogma; the wall we build around our own vision to protect it from competing views. And like all dogma‚ it is the death of dialogue and self-criticism. This is the seductive power. This is the trap it has set for us.” In his view‚ nature will always be a contested terrain and it’s meaning will always be the basis for all

What technologies have been used to kill people‚ and why? Killing technology has been on show during the major wars in the 20th century; and the killing rate increased drastically in the last century. During 20th century major developments took place in gas weapons‚ small arms‚ large guns and weapons of mass destruction which were in use during World War 1 and World War 2. Killing was not seen as an objective in war however‚ it was seen as being a more humane method and to make war shorter. The

Sheriff (1963) defined social psychology as “ The scientific study of the experience and behaviour of individuals in relation to social- stimuli situations ”as cited in Sahakian (1982).What most social psychologists study are a person’s responses stimuli originating with fellow other people. The history of social psychology can be sought at in stages. The first is the anti-democratic French crowd psychology which was around 1900‚ the democratic attitude research in the United States which was between

Same-Sex Adoption Rights Erica Sheppard Texas A&M University-Corpus Christi POLS-480 My topic is over same-sex couples being allowed to adopt children nationally. The issues with this topic are the following questions‚ “Do lesbians and gays make good parents?”‚ “Does the sexual preference of the parent have an effect on the child‚ or potential psychological effects?”. Goldberg‚ (2012) a psychologist who researches gay and lesbian parenting noted “gay parents tend to be more motivated and

up in. Here are three ways that morality is relative. Social conditioning and the environment of one’s upbringing plays a key role in determining moral value and belief. Classifying an act as moral or immoral is in itself relative to the individual. Morality is subjective‚ so certain acts are more moral or immoral to some individuals or societies than others. Therefore‚ morality is relative in

In addition many states have laws that designate which persons or entities have the authority to make adoptive placements.

RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts
