thermochemistry experiment - lab report

Objective: Does the temperature of the weewee increased or decreased as the run dry wish-wash is added both 30 seconds, until 300 seconds? What answer lead it be? (Endothermic or Exothermic reply) Hypothesis: The temperature of the water supply system testament decreased as the dry ice is added all(prenominal) 30 seconds. Also, the reaction will be endothermic reaction. Reaction: carbon dioxide+H2O → H2CO3 Technique: I will nominate a bowl that stomach fit 1000cc water. Then survey the sign temperature of the water using Pasco sensing element first. Then, I will use insulated gloves to put one dry ice each 30 seconds and see the temperature change. I will do this invariably until 300 seconds then I stop. Variable: Control - Water, 1000cc free-lance- desist ice amount, 1-10 Dependent- Temperature Background Information: change ice is rimy carbon dioxide, Co2, which can make tons of fascinating experiment. The temperature is most - 109.3°F or -78.5°C. Which is good for tutelage things cold, for example to forbid box of ice cream cold. Dry ice is inflated faster in water or else than air. It was because the water transfers modify much more quickly to the surrounding. each in water or air, dry ice can change its form, from solidity to gas. Why you have chosen this situation technique to legal profession the temperature?

I chose the particular technique to measure the temperature of the water with dry ice because this is the only way it works. Also, it is easier for me to do work and get wind the concept. What difficulties cou ld you encounter and what precautions may yo! u deal to grapple? The difficulties that I encountered during the experiment was when I needed to put a dry ice in the bowl and at the equivalent time I needed to look at the Pasco sensor to record the data. To get over this problem, I asked my maid to look at the Pasco sensor every 30 seconds and report to temperature data. Safety came first, that is wherefore I need to take the precautions in every experiment. I used insulated gloves to...If you pauperism to get a full essay, hunting lodge it on our website: OrderCustomPaper.com
