Question

which factor decide whether the animal is cold blooded or warm blooded

Answer 1

The terms are just for the same and, this does not mean that their blood is actually warm and cold.

We are aware that the animals who can regulate their body temperature are told to be warm blooded animals, such as mammals and birds who can regulate their temperature through many different process like perspiration and all.

Answer 2

It's not like that a cold blooded animal is not like that it's blood is actually cold and a warm blooded animal means it's blood is actually warm. The notation of cold blooded and warm blooded means that those animals rather organisms which can regulate their body temperature are called warm blooded animals like that of a reptile and which cannot regulate the blood temperature are cold blooded.
