Pressure and Temperature Relationships

The video tutorial explores the relationship between gas pressure and temperature. It begins with an introduction to the investigation, followed by detailed conversion calculations from psi to kPa and Celsius to Kelvin. The instructor inputs data into a spreadsheet, explaining how to handle exceptions in formulas. The video then tests whether pressure and temperature are directly or inversely proportional, using calculations and graphical analysis. The tutorial concludes with a discussion on the limitations of the data set and the potential for more accurate results with a larger range of data.
