Question

i)A gas obeying the equation of state PV=nRTatall pressures and temperatures is -------gas. a)ideal b)real c) helium d) Carbondioxide TE1
​

Answer 1

Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects to float on a water surface without becoming even partly submerged

Answer 2

Answer:

PV=nRT=

M

w

RT

Hence, PM=

V

w

RT=ρRT

ρ∝P

Here, ρ=

V

w

n=

M

w

ρ is the density, P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, T is the temperature and M is the molar mass.
