Why does ice cream get warm when you leave it out but a hot dog gets cold...?

Question

when you leave it out

Answer 1

It goes to room temp. Ice Cream warms to room temp. and hot dogs cool to room temp.

Answer 2

The temperature of all objects will eventually go into equilibrium with the surrounding (ambient) air mass.

We like to live in air that is around 20°C, but a hot dog will be hotter and ice cream will be colder than that, so the heat energy will be transferred from the warmer object to the colder object until they are the same temperature - thats called equilibrium.

The hot dog will transfer heat to the air so that the air gains heat and the air loses heat, and the air will transfer heat to the ice cream so that the ice cream gains heat and the air loses heat. When an object gains heat it will get warmer.

For example, if you have ice cream at 10°C in an infinite mass of air at 20°C, the ice cream will eventually reach 20°C. But if the parcel of air has the same mass as the ice cream, they will reach equilibrium at about 15°C. The exact number will depend on the specific heat retention of the air and the ice cream, and can be calculated with complex thermodynamic formulas.

Note that there is no energy in "cold" - cold is defined in science as the absence of heat. The heat can be transfered by a combination of conduction and radiation.

Answer 3

Law of physics said all objects are to attain equal temperature in the end.
Given a hot dog, it is hotter than the surrounding air, so it will lose heat and cool to room temperature.
Given an ice cream, it is colder than the surrounding air, so it will gain heat and warm up to room temperature.

Answer 4

It's all relative. Both items' temperatures are heading toward ambient air (room) temperature.

The ice cream has to warm up to get there, but the hot dog has to cool down.

Answer 5

because the ice cream and the hot dog are attempting to be at room temperature
since ice cream temp is a lot cooler than room temperature, the ice cream melts because it is too warm at room temp for the ice cream
the hot dog cools down because the room is too cool for the hotdog, causing it to cool down

Answer 6

its simple dude, heat flow from hot body to cold body.

hot dog is hot and so the heat goes out to environment(air) so that both are stable

ice cream is cold and heat flows from surroundings into the ice cream and so it get heat and melts and surrounding get cold but that is not noticable to humans

more easily we say, everythign try to come to room temperature.

Answer 7

Depends where you leave them out. If you leave them out on a hot stove, yes that will happen. So put the iceccream back in the freezer.

Answer 8

I easily have in no way experienced that exhilaration interior the cabinet under the stairs, yet I easily have had many relaxing cases interior the mattress room, front room, kitchen, storage, outbuilding, or perhaps in public.

Answer 9

Room temperature.

Answer 10

The temperature turns the opposite way.
