In class we decided that the rate of a reaction increases when there are more collisions or when the activation energy is reduced. We then determined that there were four ways to increase the reaction rate: increase temperature‚ add a catalyst‚ increase surface area‚ and increase the concentration of reactants. The objective of this lab was to experimentally show how temperature and surface area impact the rate of reaction‚ so only two of these methods were tested. The evidence indicates that increasing

Heart Rate Vs. Exercise & Gender Introduction The purpose of this experiment was to find out whether males or females of the same fitness levels had a higher increase in heart rate after performing the same exercise in the same amount of time. The hypothesis was that‚ with the same levels of fitness‚ females would have a higher heart rate. The main reason that this hypothesis was thought to be viable‚ was because females generally have higher heart rates than males due to their smaller heart size

School activities are those sponsored by and usually held at school but that are not part of the academic curriculum. They often involve some time commitment outside of the regular school day. A school activity serves as a break of the students from their lessons. School activities include both extracurricular and co-curricular activities. School

Well‚ they are definitely a way to escape boredom as they strive to challenge an individual to do something new by overloading or filling up his schedule. And in truth‚ there are some anecdotes on different individuals cracking under pressure due to their participation in these activities. However‚ they cannot compare to the countless rewards that these ventures have to offer. After

speed up chemical reactions without by consumed by the reaction itself (1). Enzyme activity is significantly affected by factors such as temperature‚ substrate concentration‚ enzyme concentration and pH. Enzymes are highly specific and only catalyse one specific chemical reaction‚ speeding up the reaction by lowering the activation energy‚ the energy required to start a chemical reaction (2). At high temperatures and with various mechanical forces or chemical treatments‚ proteins can denature causing

PART B YOU WILL NOW DESIGN AN EXPERIMENT TO STUDY THE EFFECT OF A FACTOR AFFECTING VITAMIN C IN FRUIT JUICES WHAT IS THE EFFECT OF TEMPERATURE ON VITAMIN C IN FRUIT JUICES? The purpose of this experiment is to determine if the difference in temperature will damage vitamin C in any type of fruit juices. Five different temperatures of fruit juices will be used(5‚ 22‚ 50‚ 70‚ 90) degree Celsius to see how temperature affects the loss of vitamin C in fruit juices. The amount of vitamin C in the fruit

Compensatory mechanism that become activated include; increase sympathetic outflow leading to arteriolar vasoconstriction‚ venoconstriction‚ and increase in heart rate; d. Increase pressure in the aortic arch will activate the aortic arch reflex and cause increased parasympathetic stimulation of the heart.
