Time to raise temperature of frozen body

[ColonelCronus]

I wanted to figure out some simple 'party' trivia, but it seems I suck a physics.

The scenario:

A bottle of wine has been placed in the freezer to cool. It is left there too long and freezes completely.

The host, fretting, decides to defrost the wine in a bucket of warm water. The water is not replenished.

How long will it take for the wine to return to liquid state?

Cheers Fellas and Ladyfolk.

I do not see any need to invoke theoretical physics when experiments can be performed very cheaply.
For a theoretcal solution the themal condutivity of the bottle would need to be obtained by measurement so why not go straight ahead and do it with wine.

You haven't given us enough information. What is the temperature of the water, the wine, how much water is the wine in, how big is the bottle, etc.

Also, have you looked up the relevant equations and such to be able to do this?

Temperature of water in the bucket: 50 deg C.
Temperature of frozen bottle of wine: -20 dec C.
Bottle capacity: 750 ml
Bucket capacity: 10 litres

Also, have you looked up the relevant equations and such to be able to do this?

Yes. Q=m c [itex]\partial[/itex]T.

I can provide some insight into the process of thawing a frozen body or substance. The time it takes for the wine to return to a liquid state will depend on several factors such as the initial temperature of the wine, the temperature of the warm water, and the size and shape of the frozen bottle. Generally, the larger the frozen body, the longer it will take to thaw.

In this scenario, the wine was initially placed in the freezer to cool, so it may have been at a temperature close to 0 degrees Celsius or 32 degrees Fahrenheit. The warm water used for thawing would need to be significantly warmer than this initial temperature in order to raise the temperature of the frozen wine. Additionally, the water should be replenished periodically to maintain a consistent warm temperature.

The process of thawing a frozen body or substance is a complex one, involving the transfer of heat energy from the warm water to the frozen material. It is difficult to determine an exact timeframe for the wine to return to a liquid state without knowing specific details such as the volume of the wine and the temperature of the warm water. However, as a general estimate, it could take anywhere from 30 minutes to a few hours for the wine to completely thaw.

It is important to note that thawing a frozen body or substance should be done carefully and under controlled conditions, as sudden changes in temperature can cause damage to the material. In this scenario, it may be best to let the wine thaw slowly in a refrigerator rather than using warm water. I hope this explanation helps in understanding the science behind thawing a frozen body or substance.
