Uncertainty = Graph 1-Plotting Volume Against Pressure * Pressure uncertainties too small to be seen. Graph 2-Plotting Inverse Volume Against Pressure * Uncertainty bars of only the first and last points are shown, as that is all that is needed to determine the slope uncertainty. * Some uncertainty values are too small to be seen. * The x-uncertainty values were used as they were larger than the y-uncertainty values. Finding Uncertainty of Slope X-Value Uncertainty-1st Point= -2nd Point= Therefore, Concluding Statement: It was found that Boyle's Law holds true since the slope of graph 2 was a linear relationship. ...read more.

Conclusion

But this is not necessarily true. Even though the pressure was being changed slowly, there still would be some changes in temperature, even though if they are extremely small. Because if the pressure changes, that means the particles have more kinetic energy, and if they have more kinetic energy, that means the temperature increases. It was also assumed that the number of mole of gas was a constant, and that none of it leaked out of the syringe. But realistically, there would have been a small amount of molecules that leaked out of the syringe. ?? ?? ?? ??

    Hence, on the basis of this, I predict that the change in enthalpy for formation of hydrated copper sulphate according to the above reaction will be negative, signifying that the overall reaction is exothermic. Therefore, I predict that the molar enthalpy change of formation of hydrated copper sulphate from anhydrous
