Answer 1

`P_2=2.6kPa`

Step-by-step 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:

`(P_2)/(T_2)=(P_1)/(T_1)`

We can solve for the final pressure as shown below:

`P_2=(P_1T_2)/(T_1)`

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

`P_2=(6.58kPa*210K)/(540K)\\\\ P_2=2.6kPa`

Which is not among the choices.

Regards!
