5.18 pound per square inch

Step-by-step explanation:

According to pressure law, the pressure of a gas is directly proportional to the temperature

P1/T1 = P2/T2

where P1 is the initial pressure = 6 pounds

T1 is the initial to temperatures = 440°F

P2 is the final pressure = Z

T2 is the final temperature = 380°F

Thus, let final pressure be Z

P1/T1 = P2/T2

6/440 = Z/380

0.0136 = Z/380

Make Z the subject formula

Z = 380 x 0.0136

Z = 5.18 pound per square inch

Thus, the final pressure at 380°F is 5.18 psi (pound per square inch)

========================================

Work Shown:

P = pressure

T = temperature

psi = pounds per square inch

P varies with T directly, so P = k*T for some constant k.

Use P = 6 and T = 440 to find k

So,

is the approximate pressure in psi that corresponds to a temperature of T = 380 degrees F.
