If you put helium in a potato will it fly?
I’m going to pretend this is a perfectly feasible problem, because I like potatoes.Anyway. I’m going to assume that by “fly” you mean lift off into the air, ie the density of the potato-helium hybrid is lesser than that of air.Now let’s assume the (raw) potato is a perfect sphere. I’m going according to the measurements in this article: Potato density changes with age - by Karim Bahsoon. Let’s also assume we start with a relatively fresh new potato of mass 142g, volume 130cm^3 and around 1.09g/cm^3 density. I’m also going to assume that you’re carving out a part of the potato to replace with helium.Let’s say you leave a border of 0.5cm around the outside of the potato and remove everything within it, (because a potato of simply potato skin is no longer a potato, and 0.5cm seems like a reasonable distance for easy cutting). Original radius of spherical potato would be around 3.14cm, and you’re removing a sphere of potato of radius 2.64cm. That means the remaining volume of the potato would be around 52.9cm^3, with a mass of 57.7g.Okay, so you’re filling up that 77.1cm^3 of space with helium. In a perfect scenario, you would be able to fill up all the space within the potato without any helium escaping. That gives a mass of 0.014g since density of helium is around 0.000179/cm^3.So the new density of your potato-helium hybrid is (0.014g+57.7g)/130cm^3 which is around 0.44g/cm^3. But the density of air is around 0.0012 g/cm^3, so I guess the potato-helium hybrid won’t float into the air after all. Of course, what is likely to happen should someone attempt this in real life is that there would be a huge cut through the potato and the helium would escape.And there go my plans of world domination through flying potatoes. :(.Please leave a comment if I’ve accidentally made any calculation errors…
Why are potato chips sold by mass rather than by volume?
Because potato chips are sold in bags, right? Sometimes bags contain more potato chips than others. More potato chips= more mass. If you're talking about the volume of the potato chip... well, stating the volume of a potato chip is an odd thing to do. and potato chips stacked together would have an irregular volume (one hard to calculate)
How many potatoes can fit on the Earth?
CREDIT:Steve Baker, Blogger at Let's Run With It! (2013-present)This question falls into the annoying category of making me do work to produce a big number that you REALLY don’t care about…and which has no practical value whatever.If I said the answer was 520,000,000,000,000,000 you’d probably be happy - I have no idea whether that’s remotely the right answer - but since you don’t REALLY care - why not?You need to learn to do these kinds of simple calculations yourself:So…in the spirit of teaching a man to fish rather than giving him a fish:Go to Wikipedia - go to the article “Earth” - look at the “info-box” to the right - where you’ll find it’s mean radius. If they give you the units in kilometers, multiply by 1000 to get it in meters. Then go to the Wikipedia article “Sphere” and find the equation for the volume of a sphere, given it’s radius. Now you know the volume of the Earth in cubic meters. Write that down.What is the volume of a typical potato? Nobody knows or cares. You certainly don’t care. So just guess: 5cm x 5cm x 10cm. That’s 0.05m x 0.05m x 0.1m. Multiply those together - now you know the volume that a a “typical” potato might occupy in cubic meters (it’s a pretty tiny number).Divide the volume of the Earth by the volume of your typical potato.Now you know the answer - it could be three times too big or three times too small - but really - who gives a damn? And you didn’t have to bother a bunch of hard-working Quora helpers with a question that really doesn’t matter a damn to anyone.enjoy :)
Potato place in different solution?
A. Potato is place in dilute sugar solution B. Potato is place in pure water C. Potato is place in highly concentrated sugar solution 1.There is no change to the size of the potato pieces in container A. Explain why? 2. Describe the changes to the size of the potato pieces in container B and C.
Find density of potato? 10 points:)?
Step 1: Find the mass of the potato using a balance. Step 2: Put water in a beaker. Determine its volume. Step 3: Put the potato in the water. Determine the new volume. Step 4: Subtract the volume of just water from the combined volume of the water and the potato. The resulting difference is the volume of the potato. Step 5: Divide the mass of the potato by the volume of the potato.
Why do potatoes retain heat so well?
The amount of heat retained (contained/held) by any object is proportional to its mass [math]m[/math] and specific heat [math]c[/math]. The mass in turn is proportional to the density [math]\rho[/math] and volume [math]V[/math].Potatoes are rich in water, which happens to have very high specific heat (4200 J per kg per K). Potatoes are fairly massive too. All that put together, you get tiny storehouses of energy.Note: retaining heat is more of a colloquial term. In technical terms, what we are trying to say is that the amount of energy released by the object as it cools is much more than that released by a lower heat capacity object when it cools through by the same amount.
A bag of potato chips contains 585 mL of air at 30.0 ∘C and a pressure of 775 mmHg .?
Initial : P₁ = 775 mmHg, V₁ = 585 mL, T₁ = (273.2 + 30.0) K = 303.2 K Final : P₂ = 458 mmHg, V₂ = ? mL, T₂ = (273.2 + 8.0) K = 281.2 K Combined gas law : P₁V₁/T₁ = P₂V₂/T₂ Final volume, V₂ = V₁ × (P₁/P₂) × (T₂/T₁) = (585 mL) × (775/458) × (281.2/303.2) = 918 mL
