How can we take pressure of ideal gas be equal to pressure of atmosphere if container is open
I can better put my doubt in form of problem:
The temperature of a gas placed in an open container is raised from $27^o$ C to $227^o$ C. The percent of the original amount of the gas expelled from the ...

Is force due to pressure equally distributed?
Pressure is defined as: $$P=\frac{F}{A}$$
My question is what if we want to find the total force in area of $\frac{A}{2}$. Would be equal to $\frac{F}{2}$? I think that is not true unless we know that ...

Why don't comets just vapourize away?
As far as I know, comets are in a freefall around the sun. That would mean, net acceleration due to gravity is almost zero because R =m (g-a) where R is reaction force. Now pressure is force per ...

Mechanical equilibrium: thermodynamics and classical mechanics
A similar question was asked here but mine is a bit different.
In thermodynamics, a mechanical equilibrium is defined as a uniform pressure (for a fluid).
In classical mechanics, equilibrium is ...
