If gas particles start colliding with the walls of their metallic container with increased force, what is their direct effect? l
2 answers:
Answer: Higher gas pressure
Explanation:
According to force and pressure relation stated above, pressure exerted is directly proportional to the force applied.
From this we can easily predict that pressure of the gas will increase when gas particles are colliding with the walls of metallic container with increased force.

Answer: The capillary rise(h) in the glass tube is = 0.009m
Explanation:
Using the equation
h = 2Tcosθ/rpg
Given
Contact angle, θ = Zero
h = height of the glass tube=?
T = surface tension =
r = radius of the tube = 0.1mm =0.0001m
p= density of ethanol =
g=
h =
h= 0.09m
Therefore the capillary rise in the tube is 0.09m
