Answer: 1.85 atm
Step-by-step explanation:
Initial pressure P1 = 1.70 atm
Initial temperature T1 = 300.0°C
Convert temperature in Celsius to Kelvin i.e (273 + 300.0°C) = 573K
Final pressure P2 = ?
Final temperature T2 = 350.0°C
(273 + 350.0°C) = 623K
Mathematically, pressure law states the pressure (p) of a gas is directly proportional to the absolute temperature (T).
i.e Pressure ∝ Temperature.
P1/T1 = P2/T2
1.70 atm/573K = P2/623K
P2 = (1.70 ATM x 623K) / 573K
P2 = 1059.1/573
P2 = 1.85 atm
Thus, the 1.85 atm of pressure is required.
