A glass laboratory flask is filled with gas at 27° C and 0.94 atm pressure, sealed and then heated to 141°C. what is the pressure inside the flask? p = ... atm

You can use the equation P₁/T₁=P₂/T₂ and solve for P₂. (P₂=P₁T₂/T₁)

anything that involves a gas usually needs to have the temperature in Kelvin instead of Celsius.

T₁=27°C+273=300K

T₂=141°C+273=414K

P₁=0.94atm

P₂ = (0.94atmx414K) / 300K

P₂=1.30atm
