If the pressure of a gas at constant volume is 4.5 atm at 100 °C, wh will the pressure be if the temperature is changed to 350 °C?

New pressure = 7.51 atm

Explanation:

Given that,

Initial pressure, P₁ = 4.5 atm

Initial temperature, T₁ = 100°C = 100+273 = 373 K

Final temperature, T₂ = 350°C = 350 + 273 = 623 K

We need to find the new pressure. Using the below relation as follows :

So, the new pressure is 7.51 atm.
