Investigation into how the focal length of a lens affects the temperature at the focal point Research & Rationale: In my project I will be looking in to how different lenses with varying thicknesses and therefore focal points magnify and intensify light passing through it. To do this I will be measuring the temperature of an object behind the lens‚ at the focal point. The study and research of lenses was not part of the course this year‚ so I thought it would be more interesting to study a new

Enzymes lower the activation energy of chemical reactions but they themselves are not consumed or altered when doing so. These catalysts work best at optimum temperatures and pH’s. The temperature and pH at which the reaction occurs the quickest is the ideal condition for the enzymatic reaction. Alpha amylase converts starch into glucose and when starch is combined with I2KI indicator a dark purple solution forms. As the enzyme breaks down the starch the absorbency will decrease. The absorbency

Investigation – Storage conditions of Bleach & it’s relation with temperature. Title/Research Question: ‘How does temperature effect the concentration of chlorate ions in bleach?’ Aim: The aim of this experiment was to investigate the optimum temperature storage conditions of bleach’s stored at different temperatures. Introduction: Chlorine bleaches are made by dissolving chlorine in sodium hydroxide solution. They have a number of uses as they are used to remove colors‚ whiten or disinfectant

evaporates‚ it lowers the temperature of the substances around them‚ because evaporation is an endothermic process. In the graph‚ each substance has a different curve. Some lowered the temperature much more than others. This is because different substances require differing amounts of energy to evaporate. To test this‚ the temperature change from the evaporation of 4 different alcohols was measured and compared‚ along with cyclohexane. Methanol had the largest change in temperature‚ 18.9 ºC. This indicates

from plants through transpiration). Drylands ’ precipitation is highly variable through the year and occurs in infrequent‚ discrete‚ and largely unpredictable events. In turn‚ the high evaporative demand of the atmosphere‚ resulting from high air temperatures‚ low humidity‚ and abundant solar radiation‚ determines that water availability is the dominant controlling factor for biological processes such as plant growth and herbivore productivity. Thus drylands‚ though not barren‚ are ecosystems of low

Alcohol and its Effects Rachael Wade Ivy Tech Community College Alcohol and its Effects Alcohol can be a very harmful substance. Alcohol can be abused‚ and people can get addicted to it like any other drug. It can impair coordination and judgment as well as a lot of other things. Alcohol can also have long term effects on the organs in the body. It can affect people psychologically as well as behaviorally. Many deaths that occur each day are caused by alcohol. Consuming alcohol affects a

thrown and there was no additional forces or resistance against or towards the device. There were only two forces put upon my device. The first was gravity pushing/pulling it down to earth. My object fell rather quickly due to its weight. Weight is the effect gravity has on the mass of an object. I had a relatively big mass‚ meaning a relatively big weight. The more weight‚ the quicker the drop. The second force was air resistance ever so slightly resisting the force of gravity. Air resistance is the action

Why does early and forced marriage happen? The causes of early and forced marriage are complex‚ interrelated and dependent on individual circumstances and context. But the practice is driven by these main factors: gender inequality – women and girls often occupy a lower status in societies as a result of social and cultural traditions‚ attitudes‚ beliefs that deny them their rights and stifle their ability to play an equal role in their homes and communities poverty – in families on a low
