Marathon running‚ triathlons‚ games of football‚ basketball‚ etc‚ require energy that is released into the blood slowly (low GI). Examples of low GI foods are baked beans‚ pasta‚ oats and most fruits. Energy Balance and Cal/KJ – what are thy and how do they work? Cal and KJ are abbreviations for the terms Calories and Kilojoules; these terms are 2 different ways of measuring energy. It can be quite confusing though as often food is measured in kilojoules and exercise in Calories. This makes it

Entropy: Entropy is a measure of the disorder of a system. Entropy comes from the second law of thermodynamics‚ which states that all systems tend to reach a state of equilibrium. The significance of entropy is that when a spontaneous change occurs in a system‚ it will always be found that if the total entropy change for everything involved is calculated‚ a positive value will be obtained. Simply‚ all spontaneous changes in an isolated chemical system occur with an increase in entropy. Like enthalpy

Iodine-Clock Activation Energy * The plot of (ln k) vs. (1/T) for the iodine clock reaction should reveal a slope of about -6230. Thus‚ (-Ea/R) = -6230. Using an ideal gas constant of R = 8.314 J/K.mol gives Ea = 6800 * 8.314 = 51‚800 J/mol‚ or 51.8 kJ/mol. Read more: Activation Energy of the Iodine Clock Reaction | eHow.com

Temperature and Thermal Energy Temperature is a measure of the average kinetic energy of the particles in a sample of matter. The greater the avg. kinetic energy of the particles in a sample of matter‚ the higher the temperature of that matter. Some temperature scales are Fahrenheit‚ Celsius and Kelvin. Thermal energy is the measure of the total kinetic energy in a sample. And Temperature
