How to lock the cross inside the jar? #shorts

Air is filled inside a jar which has a pressure gauge connected to it. The temperature of the air inside the jar is same as outside temperature (= T_(0)) but pressure (P_(1)) is slightly larger than the atmospheric pressure (P_(0)) . The stopcock is quickly opened and quickly closed, so that the pressure inside the jar becomes equal to the atmospheric pressure P_(0) . The jar is now allowed to slowly warm up to its original temperature T_(0) . At this time the pressure of the air inside is P_(2) (P_(0) lt P_(2) lt P_(1)) . Assume air to be an ideal gas. Calculate the ratio of specific heats (= gamma) for the air, in terms of P_(0), P_(1) and P_(2) .

A beaker containing a liquid is kept inside a big closed jar. If the air inside the jar is continuously pumped out, the pressure in the liquid near the bottom of the liquid will

An empty glass jar is submerged in tank of water with open mouth of the jar downwards, so that air inside the jar is trapped and cannot get out. As the jar is pushed down slowly, the magnitude of net buoyant force on the system of volume of gas trapped in the jar and the jar.

Suppose the glass of the previous problem is covered by a jar and the air inside the jar is completely pumped out. (a) What will be the answer to the problem ? (b) Show that the answers do not change if a glass of different shape is used provided the height, the bottom area and the volume are unchanged.

A barometer accelerating downwards reads 76 cm of Hg. What will be the possible air pressure inside the jar?

The translocation of substances inside a cell and over short distances in the symplast is due to the process of

A liquid is kept in a cylindrical jar, which is rotated about the cylindrical axis. The liquid rises at its sides. The radius of the jar is r and speed of rotation is Omega the difference in height at the centre and the sides of the jar is

When a gas jar full of air is placed upside down on a gas jar full of bromine vapours, the red-brown vapours of bromine from the lower jar go upward into the jar containing air. In this experiment :
