suppose you have a container v a drainpipe at the bottom full of frozen H2O i m sorry you leave a room temperature to melt. Will certainly the ice melt faster if you drain the water as it melts?

I would suppose that the water, gift warmer than the ice, will speed the melting of the ice. However, ns would likewise expect the draining the water would remove allow much more air to get in the system and also heat the ice cream faster. Which explanation is correct?

Related question: if the container is a cooler to fill with heat beverages, will the beverages cool much faster in a wet or dried ice-filled cooler?

Assuming the water and air are the exact same temperature (and that the wait is mainly stationary) then the ice will certainly melt faster in the water. This is due to water having actually a greater thermal conductivity and also heat capacity. In fact, this is straightforward to test: ar a cocktail stick v an ice cube and also lay the on peak of a glass filled ideal to the optimal with (room temperature) water. The submerged fifty percent will melt faster than that on top.

You are watching: Does an icecube melt faster in air or water

Regarding the second question: A warm object will cool much faster in icy water than in just ice because that the very same reason above but likewise because of raised surface area contact. However, icy water will certainly be warmer than simply ice. So the item will possibly be able to accomplish a lower temperature in simply ice (slow and also steady wins the race).

The ice cream in the drum will certainly melt quicker if the water is not draining out.

This is because any kind of air room between the drum and the ice cream slug will be a good insulator.

As stated in a comment every the water will stay at 0 °C until all the ice is melted. Warmth from the exterior will cause convection currents in the water and transfer heat faster to the slug and melt more. Keeping the water in will permit for a preferably of drum surface in direct contact with the inner cold water and maximise the exterior heat transfer.

There is an included bonus if the north is full, the ice cream slug will soon float complimentary and climb up to touch the lid and gain further outside surface area to help with melt at the lower mass ice temperature witch will have a slightly far better thermal gradient and so be faster.

If the air is cold yet the floor is hot then heat is mostly transferred v the bottom climate it will be much faster to drainpipe the water.
