If plane (1) contains 5 B-atoms per metre square, calculate the number of atoms that will jump from plane (1) to (2) in 1s? (Assume that on average, an interstitial atom jumps 6 times per second)

______ apparatus is used in the determination of Flash and Fire point of a lubricating oil.

Which of the following equation is related to Fick’s first law of diffusion?

______ apparatus is used in the determination of loss due to Evaporation of the lubricating oil.

Assume that on average an interstitial B-atom jumps 10 times per second. The distance between the plane is given by 2m. Then, calculate the coefficient of diffusion of B atoms? (In m²/s)

______ is the temperature at which lubricating oil ceases to flow when cooled at standard condition.

The concentration of oxygen at the inner surface of the vessel is maintained at a level C depending on the pressure in the vessel, while the concentration at the outer surface is reduced to zero by the escape of oxygen to the surroundings. A steady state will eventually be reached when the concentration everywhere reaches a constant value. Provided D is independent of concentration there will be a single concentration gradient in the wall and the thickness of the wall is L, the flux is given by________________

The acid value of an oil is the number of milligrams of ______ used to neutralize 1gram of oil.

In a hexagonal lattice on average, an interstitial atom jumps 6 times per second and that each jump is in a random direction, then the probability of the atom jumping to every one of the six adjacent sites is given by___________

Saponification value of an oil is the number of milligrams of potassium hydroxide required to saponify completely ______ grams of the oil.

Particularly violent oscillation of an interstitial atom or some chance coincidence of the movement of the matrix and interstitial atoms will result in a jump.
