Description
Lab Report: Clausius-Clapeyron Equation Ashley Wolfe 11-13-12 The purpose of the Clausius-Clapeyron Equation Lab was to measure a change in vapor pressure with temperature, and thus measure enthalpy of vaporization. The results from the Clausius-Clapeyron Equation Lab clearly indicate that through temperature change you can calculate a change in vapor pressure. Also that as 1/T decreased so did ln(Pvap), meaning that as temperature increased Pvap also increased. Our starting temperature was 278.15K and initial Pvap was 735.042 torr, as one increased so did that other one, until our final values were 354.15K and 743.569 torr. These results show that it is in fact possible to obtain Pvap from using temperature change values. Likewise that it is possible to find other unknowns when using the Clausius-Clapeyron Equation. The results did not vary from what was personally expected because as water
