d is the correct answer

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

e/c, where e is its total energy

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

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

= final temperature = ?

using the equation
