When an air bubble rises from the bottom of a lake to the surface?
When an air bubble rises from the bottom to the surface of a lake, its radius becomes double. The depth of the lake is d and the atmospheric pressure is equal to the pressure due to the column of water 10m high.
When an air bubble rises from bottom of a deep lake to a point just below the water surface the pressure of air inside bubble?
Reason: On moving from bottom to top, pressure of the air bubble will decrease, volume will increase and hence, size of air bubble will rise.
What will happen to the volume of a bubble of air found underwater in a lake?
A. i.e., volume of bubble will be almost 1.6 times to initial volume of bubble. i.e., volume of bubble will be almost 1.6 times to initial volume of bubble.
At what depth in the water the pressure will be doubled atmospheric pressure?
Pressure under water is given by the sum of atmospheric pressure and pressure of fluid. Thus, depth in water at which pressure will be equal to twice the atmospheric pressure is 10.2 m.
When an air bubble of radius r rises from the bottom?
When an air bubble of radius r rises from the bottom to the surface of a lake, its radius becomes 5r / 4 ( the pressure of the atmosphere is equal to the 10m height of water column).
Why an air bubble in water rises from bottom to top and becomes bigger in size?
The pressure under a liquid surface varies with depth. As depth increases, pressure increases. Thus, when a bubble rises from below the surface it encounters less pressure. This causes the volume to increase and the bubble rises in size as it rises from a depth.
When an air bubble rises in water its potential energy?
Potential energy of air bubble decreases, because work is done by upthrust on the bubble.
What depth of water is 1 atmosphere?
33 feet
One atmosphere is approximately equal to 33 feet of sea water or 14.7 psi, which gives 4.9/11 or about 0.445 psi per foot.
What happens to an air bubble at the bottom of a lake?
An air bubble rises from the bottom of a lake and its radius is doubled on reaching the surface. If the temperature is constant the depth of the lake is (Pressure is 1 atm above the lake) > An air bubble rises from th…
What is the pressure at the bottom of a lake?
An air bubble rises from the bottom of a lake and its radius is doubled on reaching the surface. If the temperature is constant the depth of the lake is (Pressure is 1 atm above the lake) = Pressure under water at asked depth. = Volume of bubble at original depth.
How do you find the volume of a bubble?
The air pressure is the same as the pressure of the surrounding water, and the volume of the bubble can be determined by the volume formula of a sphere V=43πr3. Now we substitute these relations into the state equation.
How do you calculate the radius of a gas bubble?
When calculating the radius of the bubble, we use the fact that the pressure of the gas inside the bubble must be the same as the water pressure in the bubble surroundings. Otherwise the pressure forces of the surroundings and of the gas inside the bubble at the air-water interface would be different and the bubble would either stretch or shrink.
