Question

A sample of a gas in a rigid container has an initial pressure of 5 atm at a temperature of 254.5 K. The temperature is decreased to 101.8 K. Based on the relationship between temperature and pressure, what must have happened to the pressure?

Answer 1

Answer:

The answer to your question: Pressure will decrease

Explanation:

Data

P1 = 5 atm

T1 = 254.5 K

T2 = 101.8 K

P2 = ?

                       $\frac{P1}{T1} = \frac{P2}{T2}$

                       $P2 = \frac{P1T2}{T1}$

                       $P2 = \frac{(5)(101.8)}{254.5}$

                              P2 = 2 atm
