this experiment‚ I am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction. I predict the higher the temperature‚ the faster the reaction rate. This is due to the kinetic theory. The more heat that is given to matter‚ the faster the particles move. This happens in the acid‚ so the faster the particles move‚ the faster the reaction rate due to more collisions between the marble chips and the acid

Reaction Turbine Nithin Mannil 08d01001 Aim 1. To investigate the Torque/Speed and Power/Speed characteristics of Single Stage Reaction Turbine. 2. To determine the Isentropic Efficiency of a Turbine. 3. To compare the characteristics of a reaction turbine at different values of inlet pressure. 4. To compare the maximum shaft power vs pressure and isentropic efficiency vs pressure. Theory Turbines are machines which develop torque and shaft power as a result of momentum changes in the

Resting metabolic rate can vary with age independently from body mass changes in the Colorado potato beetle‚ Leptinotarsa decemlineata. Abstract A study was done by Saija Pironine‚ leena Lindstrom‚ and Anne Lyytinen in the Journal of Insect Physiology‚ to investigate the age dependence of resting metabolic rate in Colorado potato beetle (Leptinotarsadecemlineata) from adult emergence until age 10 days. In their hypothesis they expected to see a bell shaped pattern in metabolic rate with adult age

The Rate Of Photosynthesis: Lab report 1) Construct a graph of your data 2) Using the graph‚ estimate the time at which 50 percent of the leaf disks were floating on the surface. The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

Heart rate investigation Research statement: To investigate‚ how diabetes affect a person’s heart rate during physical exercise. Background information: Heart rate : Heart rate is the number of time a persons heartbeats per unit of time‚ usually measured in BPM (beats per minute). Heart rate is measured by finding the pulse on body‚ usually taken from carotid artery‚ which supplies blood to the head and the neck and radial artery‚ which Is located on your wrist below your thumb

can be potentially more important for the next generation than it is for us. The issue is birth rate or population‚ what it is now and what it will be in the future. First of all‚ what is birth rate? The birth rate is the total number of births per 1000 of a population in a year. As you may know‚ by subtracting the death rate from the birth rate we will result in the rate of population. Here is a display of the birth rate from 1950 to 2015. Year Birth rate 19501955 37.2 19551960 35.3 19601965 34.9
