Agas has a pressure of 6.58 kPa at 540 K. What will the pressure be at 210 K if the volume
WARRIOR [948]

Answer:

P_2=2.6kPa

Explanation:

Hello there!

In this case, according to the Gay-Lussac's gas law, which illustrates the pressure-temperature behavior as a directly proportional relationship:

\frac{P_2}{T_2}=\frac{P_1}{T_1}

We can solve for the final pressure as shown below:

P_2=\frac{P_1T_2}{T_1}

Thus, we plug in the initial pressure and temperature and final temperature to obtain:

P_2=\frac{6.58kPa*210K}{540K}\\\\ P_2=2.6kPa

Which is not among the choices.

Regards!
