water cannot exist as liquid in.....?

Question

(a)0 degree C
(b) pressure
(c)in atmosphere
(d) 0 viscosity

Answer 1

water cannot exist in liquis state in 0 vicosity condition.
viscosity is the frictional force existing between layers.
if there's no frictional force there's easy movement of layers and that will be a perfect gas or in water vapour state.
at 0 degree water and ice state co-exist and hence water can exist in liquid state.

Answer 2

(d)

Note that the melting point of water varies with the pressure; under the right pressure conditions, it can remain liquid even at 0°C. Water can and does exist as liquid in the atmosphere, to a small degree.

However, 0 viscosity is like 0K temperature: a theoretical ideal that can never be attained by real particles.

Answer 3

actually The viscosity of water is 8.90 × 10-4 Pa·s or 8.90 × 10-3 dyn·s/cm2at about 25 °C.
as a function of temperature: μ=A × 10B/(T-C)
Where A=2.414 × 10-5 N*s/m2 ; B = 247.8 Kelvin ; C = 140 Kelvin,
so the viscocity of water depends on temperature,so 0 velocity will not be present at 0 °C.
in 0 atmospheric pressure if 0 atmosphere then we cannot hold water it wouldn't exist as a liquid.
so, all are interrelated

Answer 4

At zero degrees, water is found to be frozen and therefore, it is regarded as solid. Secondly, since water cannot be compressed, its state cannot change since a decrease in preasure will lead to a decrease in temperature.

p = kT (p= pressure, T=absolute temperature and k=constant)

In the atmosphere, water exists as vapour. At zero viscosity, this means that water will not be able to flow and since no liquid (not even liquid with the highest density) has a zero viscosity, it therefore means that water would have been transformed from its liquid state to a solid state making it stationary physically. options (a), (c) and (d) are the correct answers.
