When you take your finger off the top of a straw, the atmospheric pressure pushes the water up the straw to fill the empty space created by your finger. This is due to the difference in pressure between the top and bottom of the straw.

How do you take a ring off a finger if stuck on finger tight?

Try using soap and water to make the finger slippery. Then, gently twist and wiggle the ring while pulling it off. If that doesn't work, seek help from a professional jeweler.


How can you show that liquids transfer heat by process of convection?

-- Take a glass of water. Set it aside or put it in the fridge. -- Take another glass of water. Mix some food coloring into it, then put it in the microwave or in the oven for a short time. It doesn't have to boil, just warm it up. -- Put a straw down into the glass of cool, colorless water. -- Dribble some of the warm, colored water into the straw. The warm, colored water runs down inside the straw, and comes out on the bottom of the cool, colorless water. It just lays there for a few seconds, then it starts rising to the top, carrying heat with it. You can see exactly how it's moving, because wherever the warm water goes, the color goes. Now you can see how a pot of water gets heated through and through on the stove, and you can understand why we put the fire under the pot and not on top of it.


Why if you push your finger into a balloon and then take your finger away the dent in the balloon does not remain?

The elastic material of the balloon naturally returns to its original shape when the force (from your finger) is removed. This is due to the elasticity and flexibility of the material, which allows it to recover its original form after being stretched or deformed.

How does a boiling water vortex form and what are its characteristics?

A boiling water vortex forms when water is heated to its boiling point and starts to circulate in a swirling motion. This happens because the hot water rises and cooler water moves in to take its place, creating a vortex. The characteristics of a boiling water vortex include a central column of rising steam, a swirling motion of the water, and a relatively stable shape as long as the heat source is maintained.

What is meant by the lung pressure during inspiration is a few centimeters of water negative?

It means that lung pressure is below atmospheric (negative) during breathing in (inspiration) so that air will flow in from outside. Pressure is measured in centimetres of water, so a pressure of a few centimetres of water means the extra pressure in water at a depth of a few centimetres. Take a straw and push it into water to a depth of 3 cm with your finger sealing the top of the straw. Then take your finger off and air will come out and the water will rise in the straw. While your finger was still on the straw, the air pressure inside was 3 cm (of water). If you did the same experiment in mercury the pressure would be a lot more because it's much denser, and would be described as 3 cm of mercury.

If you rake a band aid off your finger why is it paler than the rest of your finger?

Because when you put a band aid on your finger, your locking all the moisture on that part of the finger. When that happens, your finger is really damp so when you take the band aid off after a long time then it just turns all mushy and wet. You are not really making your finger paler. Hope I Helped! 8)
