Question

Which of the following statements about hydrostatic equilibrium is FALSE? The pressure is the same at all points at the same height in a liquid in hydrostatic equilibrium. The pressure of a liquid in hydrostatic equilibrium is due to the balance between the weight of all the fluid above that point balancing the force pushing upward from the fluid below. In an arbitrary shaped container with connected open pieces, a liquid in hydrostatic equilibrium will rise to the same height at all open regions of the container. In an incompressible fluid in hydrostatic equilibrium, the pressure must be the same at every point in the fluid. Which of the following gases would you expect NOT to follow the ideal gas law? A gas with a very high density and low temperature. A gas whose temperature is well above its condensation point. A gas with a very low density. A gas that is at a very high temperature. Which of the following is a quasi-static process? A membrane separating two halves of a box with different ideal gases suddenly bursting. A piston slowly expending the volume of the container holding an ideal gas. Inflating a hot air balloon. Pepping a balloon with a pin so its gas can mix with the gas in the room.

Explanation / Answer

1) Ans Options 1

The presure at botton of the fluid , for raise h in the liquid column is denisty of fluid * g* raise in liquid colum. SO the density is same at all point in the liquid. The presure depends on the liquid only , So option 1 is false ,( as it is same at every point not only at same height)

2)answer option 1 ,

there wil be significant deviation of lideal gas at very large pressure and low temperature.,

at very large presure, density will also be high. SO at high density and low temperature.

3) Quasi static proces is a process which takes place very slowly.

SO i think , option D. peeping out air in ballon to mix with gasses in the air, as it takes place very slowly,
