AP Chemistry – Class 63

Lab Discussion: Heat of Vaporization of Water

Dates

• Period E/F  – Friday, February 1st

Big Idea: How can we determine the energy needed to change water from liquid to vapor?

Class Activity – Review Lab Processing

• shared data with Quinton [LINK]
• what is the goal of the lab?
• how is it possible to determine heat of vaporization from vapor pressure?
• what is heat of vaporization?
• what is vapor pressure?
• what do I have to plot a line?
• what units apply in the calculations?
• what do I do with “rogue data”?

Lab Reports

• steps for the lab report (see posted documents)
• lab worth 30 points – LNB worth 10 points
• lab report writing is very different from writing in other classes
• remove the “me” from all references – objectivity key
• “more” is not “better” – be concise
• follow directions
• follow directions

Homework

• Lab Report Due Tuesday
• Submit to Turnitin.com
• Turn in LNB in class on Tuesday with all lab information
