Physics What is the pressure?

Question

If I have a container of gas that holds 3.50 L that is initially at 1.00 ATM and 30.0 C, and the temperature is increased to 195C while the volume stays the same. What is the pressure now?

Answer 1

P₁/T₁ = P₂/T₂

P₁ and P₂ are initial and final pressure, respectively (in atm)

T₁ and T₂ are initial and final temperatures, respectively (in K)

• 30ºC + 273 = 303K
• 195ºC + 273 = 468K

1.00 atm/303K = P₂/468K

303P₂ = 468

P₂ = 1.55 atm (3 sig. figs.)
