State and explain Pascal's law of transmission of liquid pressure. Explain how this principle is applied in hydraulic lift.

Mention two important application of Henry's law.

State parallelogram law of vector addition and derive an expression for the resutlant of two vectors vecto P and vecto Q inclined to each other at angle theta .

What is Pascal's law? Is the law true in the presence of gravity?

State Henry's law and mention its two important applications.

State Wien's law. Write the S.l. unit of Wien's constant.

State Newton’s law of universal gravitation and hence define the universal gravitational constant G. What is its value?

Solution of two volatile liquids A and B obey Roalt's law. At certain temperature, it is found that when the toal pressure above a solution is 0.53 bar. The mol fraction. A in the vapour is 0.45 & other liquid is 0.65. What are the vapour pressures of the two pure liquids at the given temperature?

Using Stokes' Law show that the constant terminal velocity v of a sphere of radius r, density rho falling vertically under gravity through a viscous fluid of density sigma and co-efficient of viscosity eta is given by- v = (2/9).[{r^2g(rho - sigma)}/eta]

If N_2 gas is bubbled through water at 293K how many milliomoles of N_2 would be dissoved in 1 litre of water? Assume that N_2 exert sa partial pressure of 0.987 bar. Given that Henrey's law constant for N_2 at 293K is 76.48K bar.
