What type of friction is involved when an axle rotates in a sleeve?

Answer the following :
The triple-point of water is a standard fixed point in modern thermometry. Why? What is wrong in taking the melting point of ice and the boiling point of water as standard fixed points (as was originally done in the Celsius scale)?

Is it possible to open a pen cap with one finger? Why?

If the mass of all the molecules in a gas is halved and their speed is doubled, what will be the ratio between the initial and final pressure?

What is the reactance of a capacitor connected to a constant DC source?

Action and reaction are equal and opposite. Why do they not balance each other?

It is said that the assumptions of kinetic theory are good for gases having low densities. Suppose a container is so evacuated that only one molecule is left in it. Which of the assumptions of kinetic theory will not be valid for such a situation? Can we assign a temperature to this gas?
