Question

(a) what physical process occurred in this described numerical below??

(b) Consider an ideal gas contained in a cylinder with the volume 34.4L, temperature 667K and pressure 2atm.what will be pressure of the gas if it is heated at 1000k and the volume becomes 50L. 

Answer 1

a)Evaporation

$P_2=\frac {1000×2 ×34.4}{667×50}$

$P_2=2.06atm$
