Question

A gas is contained in a thick-walledballoon. When the pressure changesfrom 1417 psi topsi, thevolume changes from 0.145 L to0.878 L and the temperaturechanges from 287 K to 196 K.

Answer 1

Step-by-step explanation:

We are given: initial pressure = 1417 psi

: initial volume = 0.145 L, final volume = 0.878 L

: initial temperature = 287 K, final temperature = 196 K

To find the final pressure, we use the combined gas law:

`\begin{gathered} (P_1V_1)/(T_1)\text{ = }(P_2V_2)/(T_2) \\ \\ \therefore P_2\text{ = }(P_1V_1T_2)/(T_1V_2)\text{ = }(1417*0.145*196)/(287*0.878)\text{ = 159.81 psi} \end{gathered}`
