Down feathers are feathers that lie under a birds body and primary feathers. These feathers are small and puffy, and trap warm air under a bird's feathers.
A temperature under the freezing point.
under freezing temperature (32 degrees Fahrenheit, 0 degrees Celsius)
Well the father penguin keeps the chick warm by sheltering it under it's belly feathers
The freezing point of fresh water under normal conditions.
By freezing it - lowering the temperature - usually done by putting it under pressure

A penguin simply has skin under its feathers.
It is a scale for temperature measurement where zero degree is freezing temperature for water and 100 is its boiling point under atmospheric pressure.
Place the water in an area that has a temperature of under 0 degrees Celsius. A freezer will do.
yes they do, but they have an oil under their feathers which keeps them warm and also blubber (fat) which also keeps them warm.
There is no object that never freezes, as freezing is a natural phenomenon that occurs when an object's temperature drops below its freezing point. However, some substances, such as helium, have extremely low freezing points that make them resistant to freezing under normal conditions.
Radon is a noble gas and remains in a gaseous state at standard temperature and pressure. It does not have a freezing point as it does not freeze under normal conditions.
