Why do we burp when we drink cold drinks like cola?
A burp - sometimes also called belch - is nothing but gas. When we drink or eat , we dont just swallow liquid or food. We also swallow air at the same time.

Sometimes when we swallow gases like oxygen or nitrogen , they need to get out of the body. That's where burping comes in . Extra gas is forced out of the stomach , out of the mouth as a burp.
After drinking soda or other carbonated beverages , we burp more. The gas that makes these drinks fizzy is carbon di oxide ( CO2 ). It can bring big burps. Sometimes eating or drinking in a hurry , can make a person burp since this can send extra air into the stomach.
Extra air in = more burps out .
