Capillary condensation in nanotubes

Is anyone familiar with a recent report where liquid water has been condensed inside a carbon nanotube and then imaged with an electron microscope at very low pressure (10^-5 torr)? Supposedly the water does not evaporate at this low a pressure. Is this truly possible and why? Does anyone have the reference for this experimen ...continues

Discussion of interactive/repulsive forces

A nonelectrolyte solution adsorbs on an electrically neutral solid through a liquid. Two surfaces of this type are brought close to one another in the liquid such that they interact. Will they attract or repel one another? Which equations bear this out? How does the separation distance between the two solids come into play h ...continues

Gibbs Phase Rule

What is the consequence (what does it mean?) when a system has zero degrees of freedom as calculated by the Gibbs Phase Rule? What do I need to conclude about such a system?

The normalization constant of a Hermite polynomial

I need to figure out how to explicitly calculate the normalization facotor for the Hermite polynomial as it relates to the harmonic oscillator. N=[(a/Pi)1/2vv!]

Weight of neon

What weight of neon exerts a pressure of 20atm when confined to 2 liters at a temp of 100C?

Atoms in a molecule

As determined from the gas law, the molecular weight of a substance is eight times the atomic weight. How many atoms are in a molecule of the substance?

value of pv

What is the change in the value of pv when a gas is cooled by expansion or diffusion

thorium series

In the thorium disintegration series what element isotope is formed from the fifth emission

% by weight of helium

Assume a mixture of radon and helium is separated by diffusion. What % by weight of the gases would be helium?

Can equilibrium be maintained

When distilling toluene and benzene under equilibrium conditions can equilibrium be maintained if a) pressure is changed and if b) pressure and temp are changed? Explain by phase rule
