Molecule size?

Your parameters are not the same. 29° vs 69°.
Salt water vs "glass of water".

salt water freezes at a lower temp than fresh water. icebergs as I understand it are mostly fresh water (snow). so once you introduce salt to the equazation (spelling is hard) said fresh water becomes not so fresh and not so frozen at same temps.

and sorry my hs chemistry class didn't have access to a walk in freezer to test said hypothesis.

actually come to think of it we could have locked 20+ kids into the cafetria freezers to watch ice melt but what do i know.

Interesting experiment, I think.

Air temp of 31 in full sunlight and brine water temp of 31, which part of pure h2o ice melts fastests?

When it comes to a heat transfer medium, water will beat air any day.

That link was no help.it mostly detailed frozen sea ice (briney ice) and not freshwater floating in the sea. Melt rates and such were not included.

You let me down, Odr. Sad.

Sorry. I did say I don't know. But, I didn't say 'read'.
I said 'ask'.

In that link, at the bottom right, is a green circle with a question mark.

Click it, fill out your question. Let's see if you get an answer. Will be fun if you do.

No more sea food for me..

Despite the objections of local fishermen, the tritium-tainted water stored at the Fukushima No. 1 nuclear plant will be dumped into the sea, a top official at Tokyo Electric says.

“The decision has already been made,” Takashi Kawamura, chairman of Tokyo Electric Power Company Holdings Inc., said in a recent interview with the media.

As of July 6, about 777,000 tons were stored in about 580 tanks at the Fukushima plant, which is quickly running out of space.

As a general rule for me, if it ever lived under water, I don't eat it.

Tritium is naturally occurring and people are exposed to it every day in nature. US nuclear plants regularly release diluted tritium water. I don't think this is that big a deal.

No offense. But I don't trust the Japanese government that that will be the only thing released.

People drink Coke everyday, but too much will kill you.

http://www.physics.isu.edu/radinf/tritium.htm

..."The radioactive decay product of tritium is a low energy beta that cannot penetrate the outer dead layer of human skin. Therefore, the main hazard associated with tritium is internal exposure from inhalation or ingestion. In addition, due to the relatively long half life and short biological half life, an intake of tritium must be in large amounts to pose a significant health risk. Although, in keeping with the philosophy of ALARA, (As Low As Reasonably Achievable) internal exposure should be kept as low as practical."...

..."Cosmic rays interact with nitrogen (14N) or with deuterium (2H) and form tritium and carbon (12C). These are primarily interactions that happen in the upper atmosphere and the tritium falls to earth as rain"...

There may be a larger risk to humans from handling poorly manufactured exit signs that "glow" like radium watch dials, or broken tritium gunsights.

RISKS

Lets say you
eat your tritium rifle sight.

..."The risks from tritium are small, due mostly to:
it is a low energy beta emitter;
chemically behaves like water in the body (forms HTO or T2O - water);
has a 12.3 year half-life.
While not impossible, a large enough dose to cause any significant harm to a person is unlikely. It is a hazard, and should be treated like any other. Some basic precautions can minimize the risks, such as not handling a broken sign or sight with bare hands, ventilating an area where tritium is stored and proper disposal of used or damage tritium objects.
To help evaluate the potential risks from tritium exposure, consider the following made-up scenarios:
1) all of the activity of a rifle sight is ingested;

The rifle sights contain 12 mCi of tritium. If all of its activity were ingested, the CEDE would be 768 mrem or roughly two years of dose from natural background.

2) ten percent of the activity of a rifle sight is ingested and not recognized;

If ten percent of the activity of the tritium in a sight (1.2 mCi) would be ingested, the dose would then be 77 mrem or about two and a half months of natural background radiation."...

The atmospheric effect from Krakatoa when it exploded in 1883 is a pretty decent model for "nuclear winter". With the N Koreans doing the stupid dance, George Carlin as the Hippy Dippy Weatherman may be as correct as the climate change crowd. Compared to the N Koreans all the previous nuclear powers have been downright sane.

"I see the radar tonight is picking up a line of thundershowers, which extends from a point 9 miles south-southeast of Chester, Pennsylvania a along line and 6 miles either side of a line to a point 8 miles north-northeast of (UNINTELLIGIBLE), New Jersey.

However, the radar is also picking up a squadron of Russian ICBMs.

So I wouldn't sweat the thundershowers."

The interesting thing is going to be whether the climate change adherents will realize they are, in fact, the enemy. Will they curtail their addiction to new iToys and Amazon ditdots - all that stuff they have to have is made somewhere with an environmental cost attached.

But the real one will be when the realization hits that you can't even maintain current levels of environmental cost with population growth.

I keep saying,...We're shieting our nest and the great-grandkids are going hate us with a passion.
