How many times is the volume of a certain mass of gas at -50 C less than at + 50 C, if the pressure is the same in both cases.

To calculate the desired ratio of volumes of a certain mass of the specified gas, we use the ratio: k = Vк / Vн = (m * R * Tк / (P * M)) / (m * R * Tн / (P * M)) = Тк / Тн …
Variables: Тк – high temperature (Тк = 50 ºС = 323 К); Тн – lower temperature (Тн = -50 ºС = 223 К).
Let’s perform the calculation: k = Тк / Тн = 323/223 = 1,448 rubles.
Answer: At -50 ºС, a certain mass of gas occupies 1.448 times less volume.
