Question

Assuming volume of the container constant find out the temperature at which half air is speld out Use formula. n1.t1 = n2.t2

Answer 1

Explanation:

Since the vessel is open to the air the number of molecules of air is not fixed, but the pressure and temperature are. As the vessel is heated air will escape from it so that the pressure remains constant.

n1T1 = n2T2 ................... from PV=nRT

T2 = n1T1 / n1 ................ solve for T2

T2 = 5/5 x 300K / 2/5

T2 = 750K ............ or ............. 477C
