Question

Cylinders at a local chemical plant were filled with 385 cubic feet of cyanide gas at a pressure of 335 psi and stored at 58 degrees Fahrenheit. They were then loaded on a truck for shipment to a plastics plant. If the cylinders will reach a temperature of 120 degrees Fahrenheit while being shipped, what will be the resulting cylinder pressure?

Answer 1

We knpw that , PV=nRT;

Where, P=pressure of gas

V= volume of the corresponding gas

'n' represents mass of the gas

R= Universal gas constant

T= Temperature in the gas

Since gas is filled in cylinders and later is leak-proof, so there will be no change in volume of the gas upon changing temperature. Also mass of the gas will remain constant, so only pressure will change, when temperature will change in the given case.

Therefore, we can say, Pressure is directly

proportional to Temperature,

i,e (P2/P1)=(T2/T1)

P2=(120/58)×335

P2=693.103 psi

Therefore, the resulting cylinder pressure will be 693.103 psi.
