A sample of the inhalation anesthetic gas Halothane, in a 500-mL cylinder has a pressure of 2.3 atm at 0°C. What will be the pressure of the gas if its temperature is warmed to 37°C (body temperature)? (Hint: Which law will you apply if the volume is constant?)

The pressure will increase to a pressure of 2.6 atm

Explanation:

Step 1: Data given

Volume = 500 mL = 0.500L

Pressure = 2.3 atm

Temperature = 0°C = 273 K

Temperature is warmed to 37 °C = 310 K

Volume will stay constant

Step 2: Calculate the new pressure

p1/T1 = p2/T2

⇒with p1 = the initial pressure = 2.3 atm

⇒with T1 = the initial temperature = 0 °C = 273 K

⇒with p2 = the new pressure = TO BE DETERMINED

⇒with T2 = the new temperature = 37 °C = 310 K

2.3 atm / 273 K  = p2 / 310 K

p2 = 2.6 atm

The pressure will increase to a pressure of 2.6 atm
