Thread: what's the quickest way to change the temperature of water?

Hi all, first post

I'm wondering, in theory of course; if I wanted to cool the temp of water very fast how would I do it?

example: Say a small amount of liquid in a glass is at room temp, lets say 18c and I wanted to cool it by 10c ? what method's could be used to cool this in a second?

AND, would it be easier to cool the water if it were running over the cooling device, instead of static water?

Maximize surface contact with the heatsink. Idealized, that would be configured so that every molecule of water touches it.

In practice you cant' cool every molecule simultaneously, so you encourage already cooled molecules to make way for warmer ones. That's why ice is bad - it hogs the cold so to speak.

what's a heatsink?

how would you encourage cooler molecules to make way?

If you spray the water in little droplets into frigid air, it will freeze pretty quick. That's how the snow making machines at ski resorts work.

A heatsink is any colder thing the water conducts heat into. Then the heat sink in turn must cool itself, but that's likely easier.

You encourage cooled water to make way for warm, by moving it. You might swish the heat sink around for example. Or make the water run over the heat sink.

Harold's solution works great because with "atomized" mist every bit of water makes contact with cold air.

Thanks both for your help.

I'm looking for a solution; mixing science technology with engineering to turn my idea into reality.

Bit about me:
I'm a business man from the North-West of England. Most of my business models are service related and investment based, property, forex, stocks, etc.

I have a business plan which is product based (and invention of sorts) something I need help with.

If anyone here is interested in working together to design, create, and turn my idea into reality, please email me at: boothollie@yahoo.co.uk.

The skills I need are science related and engineering. So there may be a few of us needed.

All costs incurred will be paid for by me. There will be a confidentiality agreement to sign. The initial 'concept' of the idea will be decisive whether we move forward with it or not.

If it works it could be substantially rewarding, but as in business nothing is guarenteed.

Thanks in advance, I look forward to your replies.

The absolute best way to lower water temp asap is to expand it. Compression generates heat. squashing playdough makes it hotter and softer and this works in reverse putting water into an atmospheric pressure chamber and simulating 0 atmosphere (space) will freeze the water instantly




In practical application this is terrible, where are you gonna get an APC after all? just spray the water into a below 0 enviroment. making the water as still as possible and take up as much surface area as possible helps
