The pressure in a constant-volume gas thermometer is 0.700 atm at 1.00 3 102°c and 0.512 atm at 0°c.

(a) what is the temperature when the pressure is 0.040 0 atm?
(b) what is the pressure at 450°c?

To solve this problem we will apply the continuity and pressure and temperature ratio equations defined as

This relationship warns us that there is a proportionality between the pressure and the temperature of state one, compared to the same variables in state two.

Our values are given as,

PART A ) Rearranging to find the Temperature we have,

Therefore the temperature when the pressure is 0.04atm would be

PART B) Using the same relation but now we will find the pressure:

Therefore the pressure at 450°C is 1.35atm
