Question

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?

Answer 1

New pressure = 7.51 atm

Step-by-step 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 :

`(P_1)/(T_1)=(P_2)/(T_2)\\\\P_2=(P_1T_2)/(T_1)\\\\P_2=(4.5* 623)/(373)\\\\P_2=7.51\ atm`

So, the new pressure is 7.51 atm.
