Pretty please help me (:
Murljashka [212]

Okay I need an explanation from YOU. when is this due? If it’s last minute, why didn’t you do it when you had time? This is very irresponsible, unless you have a personal reason. Please quit commenting on others just for the points. I helped you with one, because I thought it was just one question you needed help with. No one is going to finish this for you. I’m sorry but it’s the truth, everyone here needs help. No one is here TO help. So please be cooperative and try to learn. Of course, I’m sorry if it is for a very personal reason as it happens to everyone where you need the work ASAP because of a reason. Hopefully, it’s not because you were lazy. Appreciate your education as not many people in the world have it.

A 4.700 L sample of gas is cooled from 71.0 °C to a temperature at which its volume is 3.300 L. What is this new temperature? As
Dafna11 [192]

initial condition : Vi = 4.700 L , Ti = 71.0ºC +273 => 344 K

final condition : Vf = 3.300 L , Tf = ?

Pressure is constant:

According to charle's law , volume is directly proportional to temperature at constant pressure !

Hence  Vi / Ti  = Vf / Tf

4.700 L / 344 K = 3.300 L / Tf

Tf =  3.300 L * 344 K / 4.700 L

Tf = 1135200 / 4.700

Tf = 241.53 K

Tf = 241.53 - 273

Tf = -31.47ºC
