Effects of pressure on an air bubble

AI Thread Summary
An air bubble from a scuba diver at 18.0 meters depth with a diameter of 1.0 cm will change in size as it ascends to the surface due to pressure changes. The pressure inside the bubble is affected by the external water pressure, which is higher at greater depths. As the bubble rises, the external pressure decreases, leading to an increase in the bubble's volume and diameter. The relationship between pressure and volume can be described by Boyle's Law, which states that at constant temperature, the product of pressure and volume remains constant. Therefore, the bubble's diameter will increase as it reaches the surface.

Homework Statement



an air bubble originating from a scuba diver at a depth of 18.0m has a diameter of 1.0cm. What will be the bubble's diameter when it reaches the surface?
assume constant temperature

Homework Equations



I'm not sure what equation to use for this...



The Attempt at a Solution



I know that an increase in pressure should have an effect on the size of the air bubble. But I don't know where to start.
 
Physics news on Phys.org
What is the pressure inside the bubbles? What is pressure outside the bubbles? Are they the same? Different? How does the pressure inside the bubbles relate to bubble size? Given a set number of molecules in the bubble, will a higher pressure bubble have a smaller volume or a larger volume?

Answer those questions and you will have your answer.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
