A. Comparison of Volatility by Rate of Evaporation Volatility describes how easily a substance will vaporize (turn into a gas or vapor). A volatile substance can be defined as (1) a substance that evaporates readily at normal temperatures and/or (2) one that has a measurable vapor pressure. The vapor pressure of a substance is the pressure at which its gaseous (vapor) phase is in equilibrium with its liquid or solid phase.

the difference in heart rates before and during intense exercise. Aim: The aim of the investigation was to discover how the heart rate varied with the intensity of exercise. The heart rate is a term describing the regularity of the cardiac cycle. The heart rate is the amount of times it contracts (beats) in a unit of time‚ nearly always per minute. At rest the adult female’s heart rate regulates 75 bpm (beats per minute) but this varies between people. If the heart rate is measured before‚ during

In the face of rising inflationary pressure in Hong Kong‚ some people have suggested that the Linked Exchange Rate system is the root cause of the situation and that the Hong Kong dollar should no longer be linked to the US dollar. The Financial Secretary already stated in his blog on 14 August that the Link continues to be the most appropriate exchange rate arrangement for Hong Kong. I will elaborate further on a few related issues. Many people who advocate un-pegging the Hong Kong dollar from

LABORATORY 3 The Effect of Temperature on the Rate of PNPP Hydrolysis Partners: Shelby Cruickshanks Alexis Williamson Introduction Most of the chemical reactions‚ which occur throughout our bodies‚ would proceed at a much slower rate of reaction without the presence of an enzyme. Cells can not wait for centuries for molecules to break down‚ if they waited for that‚ there would be no way for the organism to obtain energy or in turn survive. This is where biological catalyst comes into
