Answer:
The new pressure is 8.24 kPa (answer B is correct)
Explanation:
Step 1: Data given
Pressure of a sample chlorine gas = 7.25 kPa = 0.07155194 atm
Temperature = 20.0 °C = 293 K
The temperature increase to 60 °C = 333 K
The volume stays constant
Step 2: Calculate the new pressure
P1/T1 = P2/T2
⇒with P1 = the initial Pressure of a sample chlorine gas = 7.25 kPa = 0.07155194 atm
⇒with T1 = the initial temperature = 20.0 °C = 293 K
⇒with P2 = the new pressure = TO BE DETERMINED
⇒with T2 = the increased temperature = 60.0 °C = 333 K
0.07155194 atm / 293 K = P2 / 333 K
P2 = 0.08132 atm = 8.24 kPa
7.25 Kpa / 293 K = P2 / 333 K
P2 = 8.24 kPa
The new pressure is 8.24 kPa (answer B is correct)
