when milk curs it is a chemical change. A physical change is change in form, which is revesrable. Like water being frozen then thawed. A chemical change is irreversible, and involves a change in the chemical make up. What is happening is a new compound is being formed by the milk reacting with the air and such.
Turning milk into curd is a chemical change, not a physical change.
It is a chemical change.
yes...of course
No. That is a chemical change.
It is a chemical change - fermentation.
This is a chemical process.
When milk sours it is a chemical change. It is caused by lactic acid which converts the milk and makes it become sour.
Rennin is a biological enzyme present in the stomach of infant mammals. It causes the milk to solidify which slows down the digestion of the milk. This is known as coagulation or curdling. This enables the infant to absorb more nutrients and proteins from the milk before it is excreted.
chemical change Madison and Kayla were here ;)
It is a chemical change. Iron chemically reacts with oxygen to form iron oxide, or what is commonly known as rust.
Chemical or Chemical Change... I got this answer from my science teacher and its for a cross word. hope this helps!
Milk curdling is a chemical change.
Yes, but it is so hard as not to be worth it.
It is never milk again. It will just be churds and whey it will never change back. It changes the substances identity.
Melting is a phase change, which is entirely controlled by temperature (pressure is also relevant but under normal circumstances, air pressure is approximately constant). Curdling is a chemical change. The process that leads to a particular chemical is much more complicated than a change in temperature.
Chemical. It's a reaction with oxygen. If it were physical it would be fairly easy to undo...If you work out how to uncurdle milk then please let me know!
that would be much too complicated to write here. mostly it involves denaturing of milk proteins by acids or enzymes.
Curdling.
Milk turning sour is a chemical change.
chemical change
A sentence could be "I knew the milk was off because it was curdling"
ya it really effect it is the main source of curdling it.
Yes, milk turning sour is a chemical change.
