What is the work done is blowing a soap bubble of radius r?
Therefore, the work done in blowing a soap bubble of radius r and surface tension is 8πr²T.
What is the work done in blowing a soap bubble of radius R Shaalaa com?
The work done in blowing the soap bubble is 1.085 × 10−2 J.
What will be the work done in increasing the radius of soap bubble from R to 2R?
=> The work done in increasing the radius of soap bubble is equal to the increase in surface energy. Thus, the work done in increasing the radius of soap bubble will be 15πTr².
How much work is required to form a bubble of 2 cm radius from the soap?
= 7.038 × 10-4 J.
What is the work done in blowing a soap bubble from a radius of 3cm to 5cm?
2.2 × 10−3.
What is the work done in blowing a soap bubble of radius 5 cm?
(Ans : 15700 erg)
What is the excess pressure inside a soap bubble of radius 3 cm if the surface tension of the solution 30 dyne cm?
If the surface tension of liquid is 30 dyne/cm, then excess pressure inside the soap bubble is. 150 dyne/cm2. 3×10−3 dyne/cm2.
When the radius of soap bubble is increased from 1?
The radius of a soap bubble is increased from 1√π cm to 2√πcm If the surface tension of water is 30 dynes per cm, then the work done will be.
What will be the work done in increasing the radius of soap bubble from R 2 to 2r if surface tension is T?
9πr2T.
What is the work done in blowing a soap bubble from a radius from a radius of 3 cm to 5 cm surface tension of the soap solution is 0.03 nm 1?
If the size of a soap bubble is increased from a radius of 3 cm to 5 cm, the work done in increasing the size of the soap bubble is. 4π mJ.
What is work done in enlarging the size of soap bubble?
Hint: Work done in increasing the surface area of the soap bubble is the work done against surface tension. Surface tension is the tendency of a liquid surface to contract to occupy minimum area. This work done against the surface tension is the product of surface tension and the change in volume.
What is excess pressure inside a soap bubble of radius 3 cm?
A soap bubble of radius 3 cm is charged with 9.0nC. The excess pressure inside the bubble, if surface tension of soap solution = 3×10^-3 N/m is. (1)0.26N/m^2.
What is the ratio of work done in blowing up soap bubbles?
Originally Answered: Two soap bubbles have radii in a ratio of 4:3. What is the ratio of work done to blow these bubbles? The work done in blowing a soap bubble is proportional to the square of the radius. A soap bubble of radius r is blown up to form a radius of 2r under isothermal condition.
Is it possible to double the radius of a spherical bubble?
If the radius and surface tension of a spherical soap bubble be r and T respectively. Find the charge uniformly distributed over the outer surface of the bubble, is required to double radius.
How do you find the surface tension of a soap bubble?
Let surface tension on the surface of the soap bubble = T Total surface area of the soap bubble = 2(4πR2) = 8πR2 (As the soap bubble has inner as well as outer surface) Work done in blowing soap bubble = Surface tension × Charge in area
