A steel bottle contains argon gas at STP.What is the final pressure if the temperature is changed to 145°C?

Question

Quizplus · Accepted Answer

STP stands for Standard Temperature and Pressure, which is 0°C and 1 atm. Therefore, the initial pressure of the argon gas is 1 atm. 
Using the formula P1/T1 = P2/T2, where P1 is the initial pressure, T1 is the initial temperature, P2 is the final pressure, and T2 is the final temperature, we can calculate the final pressure: 
P2 = (P1 x T2)/T1
P2 = (1 atm x 418 K) / 273 K
P2 = 1.53 atm
Therefore, the correct choice is (D) 1.53 atm.
