SUMMARY
The discussion revolves around calculating the pressure of a constant volume gas thermometer at a temperature of -99 °C, given an initial pressure of 5830 Pa at 47 °C. The formula used is Pf = Pi * (Tf/Ti), where Ti is converted to Kelvin as 320 K and Tf as 174 K. The calculated pressure at -99 °C is 8.46 psi, which can also be expressed in other units such as atm. The participants clarify whether to present the final answer in psi or atm.
