# The gas inside of a container exerts 15 Pa of pressure and is at a temperature of 220 ^o C. If the temperature of the gas changes to 150 ^oC with no change in the container's volume, what is the new pressure of the gas?

The new pressure is $13.2 P a$

#### Explanation:

Use the gas law,

${P}_{1} / {T}_{1} = {P}_{2} / {T}_{2}$

${P}_{1} = 15 P a$

${T}_{1} = 220$ºC$= 493 K$

${T}_{2} = 150$ºC$= 423 K$

${P}_{2} = \frac{15}{493} \cdot 434 = 13.2 P a$
