8. • IP A constant-volume gas thermometer has a pressure of 80.3 kPa at -10.0°C and a pressure of 86.4 kPa at 10.0 °C. (a) At what temperature does the pressure of this system extrapolate to zero? (b) What are the pressures of the gas at the freezing and boiling points of water? (c) In general terms, how would your answers to parts (a) and (b) change if a different constant- volume gas thermometer is used? Explain.
