Answer:

5.18 pounds per square inch

Complete question:

If the pressure is 6 pounds per square inch when the temperature is 440° F,find the pressure exerted when the temperature of the gas is 380°F.

Step-by-step explanation:

According to the Gay Lussac's Law:

$\frac{P_1}{T_1} =\frac{P_2}{T_2}$

where, P and T are the pressure and temperature of an enclosed ideal gas.

Given:

Initial pressure $P_1$ = 6 pounds per square inch

Initial Temperature $T_1$ =440° F

Final Temperature $T_2$ =380° F

Final Pressure $P_2$ =?

Substituting all values in the formula

$\frac{6}{440} =\frac{P_2}{380}$

$P_2$ = $\frac{6\times380}{440}$

$P_2$ = 5.18pounds per square inch
