Does hot water freezes faster than cold water when kept under insulation?
The question is unclear - Which, if not both, temperature waters are insulated? Do the insulations, if both, vary? I am assuming we are purely talking liquids freezing here rather than including vapour. Cooling water down relies on the transmission of heat away from it so, assuming similar insulation: Other combinations - No, cold would freeze first. In similar conditions, hot water still has to loose the heat energy and become cold in addition to the time to chill from cold to frozen. Hot uninsulated vs Cold insulated - Possibly, depending on the insulation. If the energy loss were reduced for the cold water then if could be the case that hot water would freeze first. :-)
What is best cold weather insulation for under a mobile home?
Sealed skirt to ground level.
Is it correct to say a cold glass of water or a glass of cold water?
It depends If the water is cold and the temp of glass don;t matter than it is glass of cold water If the glass is cold and the temp of the water don't matter than it is cold glass of water People normally use glass of cold water
How will the amount of thermal energy lost by hot water be related to the amount of thermal energy gained by cold water?
The energy lost by the hot water will be gained by the cold water until they both come to equal temperature. Then there will no longer be any heat transfer from hot to cold. I think the mathematical relationship is a natural log curve that asymptotically approaches the horizontal - meaning the cooling curve keeps getting less steep over time as the heat is exchanged
Does cold water dissolve?
Yes. Cold water does disslove.
Which Insulation Keeps Water Hot or Cold the Longest?
not sure but i think styrofoam or thermocol
What kind of water bottle keeps your water cold the longest?
Stainless Steal
What type of bowl keeps ice cream cold the longest?
A metal bowl keeps ice cream frozen the longest.
Which type of cup keeps cold water hottest plastic paper metal or glass?
No, paper will not keep water cold for the longest time. A metal cup will keep water the same temperature for the longest time. I know this because I did a science experiment about this but instead of cold water I used hot, which won't really make a difference. The next would be glass then paper.
What type of cup keeps water warm the longest-plastic paper styrofoam or glass and why?
Styrofoam because it has a thick layer and is a good insulator.Paper and plastic are could alternatives but Styrofoam would work better, therefore glass would be the worst one to use because it would only keep it warm for a couple of minutes.
Why do thermoses keep things hot or cold?
It keeps the air trapped in side and has to layers with air as insulation in the middle
Why is your house warm on a cold day even though you haven't turned on the heat?
Because your house has INSULATION, it keeps the warm air in, and the cold air out.
How do you keep water cold the longest?
Ice..
Does cold water dry your skin?
no,cold wated keeps your skin refreshed its keeps your skin from getting dry
Why does the cold water tank in the attic have to be covered by insulation?
So it doesn't freeze.
What insulation should you use for a cold water pipe?
poly venal chloride
Water keeps the planet from getting to hot and cold?
no !
