a box containing 2.00m cubed of air is sealed at sea level pressure of 1.0 atm and a temperature of 20.0 degrees celsius. if the box is heated in an oven to a temperature of 250 degrees celsius, what is the final pressure in atm in the box?

assuming the air is ideal, we can use the formula,

P1/T1 = P2/T2

where

P1 = initial pressure

P2 = final pressure

T1 = initial temperature (in Kelvin)

T2 = final temperature (in Kelvin)

we first convert the given temp to Kelvin:

T1 = 20 + 273.15 = 293.15 K

T2 = 250 + 273.15 = 523.15 K

substituting,

P1/T1 = P2/T2

1/293.15 = (P2)/523.15

P2 = 523.15/293.15

P2 = 1.79 atm

hope this helps~ :)
