Pls help me it’s emergency I have exams tomorrow please

hope this ! this is not copied! search it up, it's free of plagiarism!

it was given as a lesson and guide for prayer.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
