the molecules will gain kinetic energy allowing them to move a lot more frequently. Enzymes begin a reaction when they randomly collide with the substrate molecule‚ this is where the enzyme will react upon. The speed and frequency of these collisions is dependent on the temperature‚ so an increase in temperature will effectively increase the rate of reaction and allow more products to be made. Consequently‚ an increase in the temperature will make the vibrational energy that each of the molecules

Reusable Energy: The Cleaner and Cheaper Alternative Tom Harper HUM/114 July 15‚ 2013 Mark Spinler Reusable Energy: The Cleaner and Cheaper Alternative Over the past ten years‚ reusable energy has been the topic of so many law makers and just about every American tax payer around. As the energy rates continue to rise‚ we are constantly looking at new ways to save on household energy costs. We conserve energy by turning off lights‚ washing clothes during early morning or late evening hours

Energy conservation refers to reducing energy consumption through using less of an energy service. Energy conservation differs from efficient energy use‚ which refers to using less energy for a constant service.[1] For example‚ driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques. Even though energy conservation reduces energy services

Solar Energy Topics Solar technologies use the sun’s energy and light to provide heat‚ light‚ hot water‚ electricity‚ and even cooling‚ for homes‚ businesses‚ and industry. More basic information about solar is also available. Solar Technologies Photovoltaics (PV) Photovoltaic solar cells‚ which directly convert sunlight into electricity‚ are made of semiconducting materials. The simplest cells power watches and calculators and the like‚ while more complex systems can light houses and

My topic for the science fair project is "The effect of temperature in energy loss in a basketball". Some of my subtopics for my project include the pressure air and height in a basketball‚ the material a basketball is made out of and the size of the ball. Different sports require different size balls to correspond with the correct bounce it needs to be used during the sport. Thats why you would not be able to use a tennis ball to play basketball because it is too bouncy and a soccer
