this article alone was sufficient to get my thermodynamics right.

CH3CO, as I guessed but how do you use it in nomenclature in a standard way.

refer to the second paragraph, in bold text. https://www.grc.nasa.gov/www/k-12/WindTunnel/Activities/Pascals_principle.html

Consider a conventional U-tube with both the vertical tubes having the same uniform cross section area A and the horizontal tube of length L, connecting those tubes containing an ideal liquid. Now the free surfaces in both the vertical tubes will be at the same height and will have pressure...

What does it mean and why do acetophenone and acetic acid have it in their name ?

How did you tell this isn't steady?

So what's the final conclusion about pressure in simpler terms.

Consider a fixed horizontal tube of uniform cross section with pressure being 1atm at one of it's end and 5atm at the other (former due to 'open to atmosphere' and latter due to force on a piston), then liquid would flow towards low pressure end. By equation of continuity all cross sections will...

I know how to solve problems of eudiometery but i don't understand a really basic thing ie how come gases occupy different volumes in an eudiometery tube. (For eg: 15ml of hydrocarbons with 320ml other gases). Gases occupy entire volume of the container, right. So shouldn't all gases occupy the...

Yes the disk is a metal one. Its just that a single point on disk having two pressure 100/A on one side and 30/A on the other was something unusal because i have mostly calculated only one pressure value for a point.

Measuring device is the one which divides normal force downwards by g. But i have seen people describing Buyoant force as change in the weight of an object(which sinks. Weight is constant but the normal force on its base, which would be measured by the machine is the new weight), where the new...

I was talking about theoretical case like those involving calculations on moment of inertia of circles, rectangles about a axis etc, assuming they have weight and dealing with 1 dimensional objects (points) in force and laws of motion.

We say that buyont force act upwards (in usual cases) and that the normal force exerted by the base of a container (of liquid) on a object is less than its true weight, so a weghing machine will give smaller reading (in terms of value) than expected. But suppose a cube sinks in water. Now water...

thank you for replying, but are you saying that each point on the surface will have 2 values of pressure ? In hydrostatics I was told that each point of the liquid will have only one pressure value by Pascal's law(P=p+xdg, where p is pressure at free surface, g is g effective(resultant of pseudo...

Suppose there is a circle with area 'A' and on one of the faces of the circle a force of 100N is applied and on the other face a 30N force is applied (since all 2D surfaces have 2 faces) such that these forces are opposite to each other, perpendicular to the faces, and forces are equally...
