boyle's law
...e clicked the button marked “REC” until a keyboard sampling dialogue box opens. As I mentioned before in entry 1, we typed 21.0 ml. And, then we slowly pushed on the plunger on the syringe until it reaches 18 ml marked and we noted the pressure. 4. We did the procedure for the reaming reading entering the series of reading of 2 ml intervals each. And, we wrote the data displayed and calculated by the computer. 5. Then, we clicked “stop sampling” button in the keyboard. Sampling window and recorded the final room temperature in Celsius. Then, we printed the data and the graph. 6. We calculated the rms (root-mean-square) deviation and the percentage rms deviation of the PV products using the equations given in the book. Question and Answers: 1) Would an error be introduced into on experiment if the room temp should change? Yes, an error can occur in this experiment if the room temperature changes. First of all, the Boyle’s Law is [(P1V1)/T1] =[(P2V2)/T2], where besides pressure and volume, the temperature is also a key factor in Boyle’s Law. In this experiment, we measured that the temperature T2 and T1 are held constant in deriving the formula for equation 1; PV=C or P1V1=P2V2. Therefore, changing temperature can contribute to the percentage error in this experiment but it is proved that as the pressure increases, the volume decreases. And, as volume decreases the pressure increases. 2) Dose Boyle’s Law hold accuracy at very high and very law temperature or pressure? For this experiment, the kinetic energy plays a big role. As kinetic energy increases, at some point, the temperature also increases. The Boyle”s Law states that the products of pressure and volume is constant for a fixed mass of gas held at a constant temperature‘t’.[(P1V1)/T1]=[(P2V2)/T2], so [(P1V1)]=[(P2V2)],- this equation is correct if the initial and final temperature is constant for both time periods. So, it means that the relationship between the temperature and the pressure. So, YES, the accuracy of Boyle’s Law does depend on the different in T and pressure. Discussion and Analysis: The purpose of this experiment is to investigate how the volume of gas varies with the pressure at constant temperature. The percentage rms deviation of the PV that resulted is 1.69%. According to the Boyl...
