an additional respective tube. This decision was enacted for the mere purpose of conserving time; however, in doing so, admittedly the control variable of “laboratory apparatus setup” had been compromised. 4.Uncertainty of thermometer and graduated cylinder. The thermometer uncertainty is especially large; a 1℃ difference is, in regards to the objective of such experimentation, highly significant. 5.Anomalous “eruptions”. One startling observation which could not be explained definitely had…

other materials included the still head, 10 mL graduated cylinder, 2 pipettes, support plate, the long distillation column, rubber connector with support rode, 2 ring clamps, an additional rubber connector, copper turnings, sand bath, ring stand, a thermometer adapter, and a thermometer1. Before assemble of the distillation apparatus could begin, the 50/50 mixture of ethanol and water needed to be prepared. Using a pipette, 2 mL of water was…

approximate boiling point of ethanol from when the liquid boiled, such as if the thermometer read incredibly below 78 degrees celsius, than this temperature was most likely the atmospheric temperature. Fractional Distillation differs from Simple due to the fractional column that is filled with beads and cylinders that the vapor gas of ethanol climb through first before reaching the three way adapter, the thermometer, and the condenser tube. Chem Helper states that these beads act as theoretical…

In the time win Galileo Galilee wanted to a Science ear. Galileo farther want Galileo to be a to study medicine to be a Dr. Galileo want to be science. Well Galileo did go to the University of Pisa to study medicine. I to make his farther happy. Galileo Galilee was born in Italy February 15,1564. Galileo died in Artery Italy on January 8,1642.Galileo was 77 years old and he was the 7 oldest children. Galileo father was a musician and wool trader. Galileo father wanted Galileo to study medicine…

Stir the water carefully with your thermometer and periodically read the temperature without lifting the thermometer out of the water. Continue this process until the temperature stops increasing. Write down the final temperature. 8. Now you can use equation 12.1 to determine how much heat the metal transferred to the water…

J/g℃. The percent error of that calculation is 32.299%. A considerable reason for this error is inaccurately reading the thermometer to the tenth degree digit (0.1℃). The atomic mass of Copper calculated is 95.038g/mole while the actual atomic mass is 63.548g/mole yielding a percent error of 49.553%. The error calculated can still be attributed to inaccurately reading the thermometer when gathering data. The final calculation made was using the entire class data and plotting it on a graph in…

limitations to the data in this lab. When measuring temperature, stirring of the thermometer had a big effect. The stirring, however, wasn't very consistent throughout all three trials which may have caused inaccuracies. The equipment may have also been a limitation in this lab. The scale used to measure the calcium chloride only went to tenths of a gram which could have made the masses inaccurate. Also the thermometer used only measured to single degrees and may not have been as accurate as a…

moving. Temperature is important in all fields of natural science, such as physics, geology, chemistry, space science, medicine, and biology, it is also used in our everyday lives. It is measured by a thermometer. Thermometers have a liquid inside of them, when it is hot out the liquid inside the thermometer expands so it goes up and when it’s cold the liquid gets smaller so it goes…

BTEC Subsidiary Diploma in Construction & the Built Environment Unit 4 – Construction Science and Materials Assignment 1 Human Comfort within Buildings Report Student: Peter McCaughey Teacher: Mrs Keyes Scenario A property developer is converting an old railway station into retail and office accommodation. The client is keen to make the working environment for the staff as comfortable as possible. As a consultant, explain how this can be done by addressing the relevant grading criteria.…

Weather is something that the world faces on a daily basis. The art of weather forecasting began with early civilizations using reoccurring astronomical and meteorological events to help them monitor seasonal changes in the weather (Griffin, 2005). During the 1800s, weather observations began to grow and expand across the United States (Uccellini, 2015). During the 19th century weather observations from distant points could be rapidly collected and analyzed at one location (Uccellini, 2015). The…
