Answer:

option (c)

Explanation:

A small diameter open tube is called capillary tube.

When a capillary tube is immersed in a vessel containing mercury, then the mercury falls in the capillary tube and the shape is like outside of an umbrella.  

As the angle of contact for mercury and glass is obtuse, so it falls in the tube and the meniscus is convex.

The answer is A .
Due to air pressure, the mercury in the tube will be higher than that in the vessel.
Mercury in a container, the center of the liquid is always higher, so it is shaped like the outside of an umbrella.

Which statement describes the magnetic field inside a bar magnet?
kakasveta [241]

The statement that describes the magnetic field inside a bar magnet is as follows: it points from north to south.

<h3>What is a bar magnet?</h3>

A bar magnet is a permanent magnet of rectangular shape.

A magnet generally possess a magnetic field, which is a condition in the space around a magnet which there is a detectable magnetic force and the presence of two magnetic poles.

A bar magnet like every other magnet possesses a magnetic field that points from the north pole to the south pole.

If the temperature is held constant during this process and the final pressure is 683 torrtorr , what is the volume of the bulb
Anna [14]

Answer:

Explanation:

Let the volume of the unknown bulb = X L

The volume of the system , after opening valve = (X + 0.72 L )

Use Boyles law gas equation,

P1V1 = P2V2 ( at temperature is constant )

Given:

P1 = 1.2 atm

P2 = 683 torr

Converting mmHg to atm,

1 atm = 760 mmHg(torr)

683 mmHg = 683/760

= 0.8987 atm

1.2X = 0.8987*(X + 0.720)

1.2X = 0.8987X + 0.6471

0.3013X = 0.6471

X = 2.15 L
