Question

how is curdling endothermic.....plz explain in simple words​

Answer 1

Answer:

One of the defining features of mammals is that they're warm-blooded - at least, when they're not hibernating. The only other living creatures that are truly warm-blooded are the birds... but what exactly do we mean by 'warm-blooded', anyway?

Answer 2

Curdling occurs when the proteins in a sauce denature and bind together, separating from the water and tightening up into curds.

For this reaction is consumes heat to separate water and proteins.
