discovered that relationships between pressure‚ volume‚ and temperature were constant across types of gas. These early laws gave rise to the combined gas laws and the ideal gas laws. Charles’s Law Charles’ Law shows a direct relationship between the volume of a gas and the temperature of the gas. As with most things‚ as the temperature of a gas increases so does the volume. This law is shown as: Keep in mind that this scientific relationship only works for the same gas at two diverse temperatures

Charles’s Law – Lab Report Charles’ Law: Assuming that pressure remains constant‚ the volume and absolute temperature of a certain quantity of a gas are directly proportional. Mathematically‚ this can be represented as: Temperature = Constant x Volume or Volume = Constant x Temperature or Volume/Temperature = Constant Substituting in variables‚ the formula is: V/T=K Because the formula is equal to a constant‚ it is possible to solve for a change in volume or temperature using a proportion

DISCUSSION The quantitative relationship between the volume and the absolute temperature of a gas is summartzed in Charles’law. This law states: at constant pressure‚ the volume of a particular sample of gas is directly proportional to the absolute temperature. Charles’ law may be expressed mathematically: V ". T (constant pressure) V = kT o‚ : T = k (constant pressure) (1) (2) where V is volume‚ T is Kelvin temperature

According to Charles’ Law‚ temperature and volume increase proportionally‚ as long as chemical amount and pressure remain the same. Research Question: How does the volume of a balloon react to changing temperatures? Hypothesis: If we increase the temperature

Fixed Income Zero coupon bonds Professor Anh Le 1 – Zero coupon bond and zero yields A zero coupon bond (or zero for short)‚ as its name suggests‚ is a bond that pays no coupons. It only pays the face value on the maturity date. Not surprisingly‚ sellers of zero coupon bonds have to offer them at a deep discount in order to sell them to the public. For example‚ a 30‐yr zero‚ face value $1‚000 could be selling for as little as $53.54. One question you may ask right now is: i

Coke often rejected it anyway because of its aspartame-sweetened aftertaste. “What we were seeing before Zero launched was that more and more younger people were interested in no-calorie beverages but weren’t going to sacrifice taste‚” Bayne said. “So when they got interested in no-calorie‚ they were like‚ ‘Forget it‚ I’m not going to Diet Coke.’” Testing showed that the name “Coke Zero” would be an effective way to sell a low-calorie cola to men without using the word “diet.” And advances

upon a time there was no zero. Of course people knew if they had nothing‚ but there was no mathematical notation for it. Zero was independently invented only three times. The first recorded zero is attributed to the Babylonians in the 3rd century BC. A long period followed when no one else used a zero place holder. But then the Mayans‚ halfway around the world in Central America‚ independently invented zero in the fourth century CE. The final independent invention of zero in India was long debated

Explain the differences between absolute and relative morality (25 Marks) There are numerous differences between absolute and relative morality which people use to base their everyday life choices‚ deciding whether an action is moral or immoral. Absolute morality is the view that actions are deontological‚ paying no attention to circumstances of when an action was performed‚ being a fixed decision‚ with no possibility of alteration. People who believe in this‚ consider consequences equal for all

Though he owns several banks‚ Merali says one may not believe that his personal bank account balance sometimes reads zero. He discloses: “I have made a decision to give 50% of my annual earnings to charity. However‚ sometimes I exceed the limit and find I have given 100 per cent”‚ he says with a shy smile.
