FactChecker replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.I don't expect "infinite controls". I would just encourage you to be reasonably careful about your experiment before you expect good... -
FactChecker replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.Good point. That makes the measurement of weight that others have recommended more important I can't judge the volume of the collapsed...

Like.
A simple controlled procedure to remove thermal contraction as a confounding factor: 1. Fill the bottle completely to the brim with... -

If I were observing volume changes of a plastic bottle, I would, measure the mass before and after by placing the bottle on a kitchen...

When a plastic bottle collapses in one direction, it gets larger in another, creating an elliptical cross section or even more crumpled...

FactChecker replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.Some of those photos show a LOT of loss of volume. IMO, that much shrinkage is hard to explain. And it is very pronounced in some...

Informative.
The volume expansion from water to ice is an intrinsic property of water specifically under the constraint of negligible confining... -

I froze a plastic bottle full of water (as near to mo air as I could manage) and put it in a bowl of water. It floated: And a crop of...

FactChecker replied to the thread A question about quantum entanglement.IMO, you are putting words into my mouth. I reasonably thought that we were discussing the SR theory of what is happening now, locally...

@LightningInAJar , doesn't @Filip Larsen 's post #8 give you everything you've asked for?

FactChecker replied to the thread A question about quantum entanglement.Mathematically, with very reasonable/desirable assumptions, there are only two possibilities, and only one with a constant speed of...

FactChecker replied to the thread High School Good drawing of Earth's orbit for model? Possibly vector file?."Perfect" is a very strong requirement. The Earth/Moon combination is nearly perfect. The Earth alone will be influenced a tiny bit by...

FactChecker replied to the thread High School Good drawing of Earth's orbit for model? Possibly vector file?.That's an important clarification.

I wanted to make the model just to give a visual of the weather of a given year. The cause of weather change doesn't matter to me. Just...

FactChecker replied to the thread A question about quantum entanglement.After precise experiments that measured the speed of light as c, no matter what the velocity of the test platform was, I think it was...
