The pressure inside a hydrogen-filled container was 2.48 atm at 21 oC. What would the pressure be if the container was heated to 84 oC ?

3.01 atm

According to Gay-Lussac's law, the pressure (P) of a given mass of gas when volume is left constant is directly proportional to the kelvin temperature (T) of the gas. i.e

P ∝ T

P = kT

Where;

k = proportionality constant

=> = k

=> =        -------------------(i)

Where;

and are the initial and final pressures of the gas

and are the initial and final temperatures of the gas

From the question;

= 2.48 atm

= ?

= 21°C = (21 + 273)K = 294K

= 84°C = (84 + 273)K = 357K

Substitute these values into equation (i) as follows;

=> =

Solve for

=

= 3.01 atm

Therefore the pressure will be 3.01 atm
