Answers
The can will burst at 938.45 K.
What is Gay Lussac's Law ?Gay Lussac's Law states that the pressure of a fixed amount of gas is directly proportional to the absolute temperature at constant volume.
i.e. P ∝ T
P= KT
P₁ = KT₁
P₂ = KT₂
Here we have considered that the gas is at two different temperatures and pressures which is denoted by T₁ , T₂ and P₁ , P₂
It can also be written as
(P₁ /P₂ ) = (T₁ / T₂)
It is given that
P₂ = 14.29 atm
P₁ = 4.535 atm
T₁ = 298.15 K
T₂ = ?
T₂ = (298.15 * 14.29 )/ 4.54
