The inside of a snowman could be warmer than the outside.
If you built a snowman during the day the snow only needs to be below freezing. It can get colder that night or the next day by quite a bit. The exterior of the snowman would be colder than the inside even though they're both frozen.
Snow is porous (unlile water it came from, or ice) so it is a pretty good insulator. So yeah it would be warmer inside the snow man.
You can even build a really big one, sit inside it and light a campfire to stay warm :)
Light a fire inside a big snowman? I don't have igloo what you're talking about.
Ice also has a fairly high specific heat capacity, which means that changing the temperature means there’s lots of energy involved. Energy can’t just leave the ice at whatever rate you want, which means there’s a potential bottleneck.
As the environment cools down during a clear skies, there a lot of energy trapped inside the snow, and it’s leaving at some slow pace. Even when there’s less heat in the snow, that change translates to a very small difference in temperature. The air around it can also cool down much faster, which means that the temperature difference can be surprisingly big.
This is kinda how igloos work. They hold the heat from the ground below and the occupants inside. The interior is cold, but not nearly as cold as the sub-zero temperatures outside.
That's why they spray water on fruit trees, to insulate them at 32F, right?
Tauntauns are warmer on the inside, too.
Are you speaking from personal experience?
Put your dick in it and find out.
