A scientist discovers a new thermometer which reads temperature in a new unit called the degree Gator,G0. Careful measurements of an ideal gas in a closed, constant volume container indicate that the pressure of the gas is 8.80 atm at 41.3 G0 and 11.33 atm at a temperature of 90.1 G0. What is the absolute zero of temperature of the Gator temperature scale?
Exactly 5.02 grams of an unknown gas was sealed in a 3.0 L flask at 37.0oC and a pressure of 1.25 atm.
