A vapour is said to be saturated when?
more molecules return to the liquid than leave it
a dynamic equilibrium exists between the liquid molecules and the vapour molecules at a given temperature
the vapour pressure is atmospheric
the temperature of the vapour varies
all molecules are moving with the same speed
Correct answer is B
A vapor saturated is said to be in a dynamic equilibrium with its own liquid
3.3cm
6.5cm
7.5cm
10.8cm
15.0cm
Correct answer is C
F α e and m α F
m1e1 = m2e2
105 = 15e2
e2 = 7.5cm
