Is the ‘fog’ observed when the pressure in the bottle is high or when it is low?
A container is filled with hydrogen gas at a pressure of 15 atm at 15^@C . At what temperature will the pressure inside the container be 30 atm ?
A 10.0 L container is filled with a gas to a pressure of 2.00 atm at 0^(@)C . At what temperature will the pressure inside the container be 2.50 atm ?
What happens to the pressure inside a soap bubble when air is blown into it?
What is the pressure inside a drop of mercury of radius 3.0mm at room temperature? Surface tension of mercury at that temperature (20^(@)C) is 4.65xx10^(-1)Nm^(-1) . The atmospheric pressure is 1.01xx10^(5)Pa . Also give the excess pressure inside the drop.
Assertion (A): When a gas at high pressure expands against vacuum, the work done is maximum. Reason (R ) : Work done in expansion depends upon the pressure inside the gas and increase in volume.
Statement-1. The pressure inside the LPG cylinder remains constant even what it is in use at room temperature. Statement-2. Pressure on the liquid is independent of its mass.
A soap bubble has radius R and thickness d(ltltR) as shown. It colapses into a spherical drop. The ratio of excess pressure in the drop to the excess pressure inside the bubble is
The excess pressure inside a soap bubble is
What is the need for smoke particles inside the bottle for this experiment?
