thermochemistry experiment - lab report

Objective: Does the temperature of the weewee increased or decreased as the modify screwball is added both 30 seconds, until 300 seconds? What answer lead it be? (Endothermic or Exothermic reply) Hypothesis: The temperature of the body of peeing give decreased as the dry ice is added all(prenominal) 30 seconds. Also, the reaction will be endothermic reaction. Reaction: carbonic acid gas+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 both 30 seconds and see the temperature change. I will do this eternally until 300 seconds then I stop. Variable: Control - Water, 1000cc free-lance- refrain ice amount, 1-10 Dependent- Temperature Background Information: change ice is wintery carbon dioxide, Co2, which can make tons of fascinating prove. The temperature is approximately - 109.3°F or -78.5°C. Which is good for tutelage things cold, for example to hang in box of ice cream cold. Dry ice is towering faster in water or else than air. It was because the water transfers passionateness much more quickly to the surrounding. each in water or air, dry ice can change its form, from unscathed 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 ascertain the concept. What diffi culties could you encounter and what precaut! ions may you wish 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 mortify this problem, I asked my maid to look at the Pasco sensor all 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 necessity to get a full essay, hunting lodge it on our website: OrderCustomPaper.com
