<i>1. State the five assumptions of the Kinetic-Molecular Theory of gases.</i><br><br>a) Gases consist of large numbers of tiny particles. These particles‚ usually molecules or atoms‚ typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids.<br><br>Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared

Empirical and Molecular Formula | Key Concepts * Empirical Formula of a compound shows the ratio of elements present in a compound. * Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound. * The empirical formula mass of a compound refers to the sum of the atomic masses of the elements present in the empirical formula. * The Molecular Mass (formula mass‚ formula weight or molecular weight) of a compound is a multiple of the empirical

arena. I had my first glimpse at molecular biology then. But that brief introduction to molecular biology was enough to compel me to the idea that I want to spend my whole life working and conducting research on it. That passion and zeal brought me to where right now I am. I have successfully completed my masters from the Department of Genetic Engineering and Biotechnology‚ University of Dhaka. I want to note that very few universities offer courses related to molecular biology here in Bangladesh but

Section (A) Q: How high do the maintenance margin levels for oil and gold have to be set so that there is a 1% chance that an investor with a balance slightly above the maintenance margin level on a particular day has a negative balance 2 days later? How high do they have to be for a 0.1% chance? Assume daily price changes are normally distributed with mean zero. Explain why the exchange might be interested in this calculation. Answer: Required Maintenance margin level for crude: Based on the calculation

The Organisation Level of an Organ System. There are 11 organ systems in the body such as the reproductive system‚ digestive system and the cardiac system. The first level organisation is the organelles which collect together to produce a cell. The organelles all have a function in the cell to keep it alive. For example the mitochondria is an organelle in a cell which has the role of respiration in the cell. The mitochondria produces ATP which involves contracting muscles‚ taking part in cell division

Conflict took place when people journeyed across America across the harsh terrains‚ and conflict still occurs today in our every-day lives. One way conflict is shown is in Progress of America (Doc 2). Conflict was shown in many ways during the

Leakages and injections have a great influence on economic activity‚ as they basically are economic activity. Without leakages and injections there would be no circular flow‚ without which the economy would run as it does now. The government also plays a major role in the running of the economy as it has a great influence over what goes in and out of the circular flow by the way of taxation‚ imports and exports. The five-sector circular flow of income model is a theoretical way for economists to

The 7 levels of Hearing Loss When you hear the word ‘deaf ’you tend to associate it with someone having complete hearing loss‚ this is not always the case. As most of us have noticed the elderly tend to not hear well‚ this is because as we age we progressively lose hearing‚ especially high frequencies. When it comes to being deaf or having hearing loss there are seven common levels or stages of it. They are known as: Normal Hearing‚ Mild-‚ Moderate-‚ Moderately Severe-‚ Severe- ‚ Profound-‚ and
