Ответ:
The pressure would be 4 atm
Further explanationGiven
gas at STP(1 atm, 273 K)
T₂ = 819 °C + 273 =1092 K
Required
The peressure
Solution
Gay Lussac's Law
When the volume is not changed, the gas pressure is proportional to its absolute temperature
P₂ = (P₁.T₂)/T₁
P₂ = (1 atm x 1092 K)/273 K
P₂ = 4 atm
