Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

Newton’s Law of Cooling The main purpose of this experiment was to find the positive constant “K” for different liquids in the Newton’s Law of Cooling equation‚ in order to determine when it was safe to store food products in commercial restaurant after cooking. The high risk temperature for bacteria growth is between 5 and 60 degrees. However putting hot food into your fridge before this point can cause food poisoning especially in deep containers‚ which is why it is vital that food companies

the heart‚ it increases which makes the left ventricle expand and adapt to a different situation. Due to this‚ the heart can register a higher level of blood and eject it at a faster rate to all living cells and membranes. This increases the heart rate because the movement of blood is faster than the resting heart rate. When performing a strength training exercise‚ the muscles contract allowing blood vessels to pass in and out. This builds the pressure in the body as well as increases the amount of

He broke suicide into four types. Egoistic suicide comes from a prolonged sense of not belonging. Altruistic suicide is the sense of being overwhelmed by the goals or beliefs of a
