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 from a radius of 3 cm to 5 cm surface tension of the soap solution is?

6.6 × 10−3.

What will be the work done in increasing the radius of soap bubble from R 2 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 do you find the work done in blowing a soap bubble?

● Explanation –

1. # Given – T = 0.06 N/m. r1 = 2 cm = 0.02 m. r2 = 5 cm = 0.05 m.
2. # Solution – The work done in blowing a soap bubble is – W = T × ∆A. W = T × 8π(r2^2-r1^2) W = 0.06 × 8×3.142 × (0.05^2 – 0.02^2) W = 0.003167 J.
3. W = 3.167×10^-3 J. Hence, work done in blowing a soap bubble is 3.167×10^-3 J.

What is the work done in blowing a soap bubble of radius 5 cm?

(Ans : 15700 erg)

What is the work done in blowing a soap bubble of radius 0.2 Metre?

4π×10−4J.

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.

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 is the excess pressure inside a soap bubble?

Directly proportional to square of its radius.

What is the excess pressure inside air bubble?

Consider an air bubble of radius R inside a liquid having surface tension T as shown in Figure 7.28 (a). Let P1 and P2 be the pressures outside and inside the air bubble, respectively. Now, the excess pressure inside the air bubble is ΔP = P1 − P2.

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 the work done in blowing a soap bubble?

The work done in blowing a soap bubble of radius R is W. The work done in blowing a bubble of radius 2R of the same soap solution is 4W. where, T is the surface tension and A is the area of soap bubble.

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
