Answer:
The new pressure of the gas is 95.54 atm or 72610 torr
Explanation:
Step 1: Data given
Volume of the cylinder = 5.4 L
The initial temperature = 32.5 °C = 305.65 K
The initial pressure = 673.2 torr = 0.88578947 atm
The volume decreases to 0.13 L
The temperature is increased to 520.5 °C = 793.65 K
Step 2: Calculate the new pressure
P1*V1 / T1 = P2*V2/T2
⇒with P1 = the initial pressure =673.2 torr = 0.88578947 atm
⇒with V1 = the initial volume = 5.4 L
⇒with T1 = the initial temperature = 32.5 °C = 305.65 K
⇒with P2 = the final pressure = TO BE DETERMINED
⇒with V2 = the final volume = 0.13 L
⇒with T2 = the final temperature = 793.65 K
0.88578947 atm *5.4 / 305.65 = P2 * 0.13 / 793.65
P2 = 95.54 atm = 72610 torr
The new pressure of the gas is 95.54 atm or 72610 torr
