Answer 1

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.

Explanation:

According to the Gay Lussac's Law:

`(P_1)/(T_1) =(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

`(6)/(440) =(P_2)/(380)`

`P_2` =
`(6*380)/(440)`

`P_2`= 5.18pounds per square inch
