Question

What do these two changes have in common? Milk going sour grilling a hamburger.

A) Both are chemical changes
B) Both are physical changes
C) Both involve heat as a factor
D) Both result in a change of state

Answer 1

Both the milk going sour and grilling a hamburger are examples of chemical changes where new substances with different properties are formed.

Step-by-step explanation:

Both changes have in common that they are chemical changes. Milk going sour involves the breakdown of sugars and denaturation of proteins, resulting in the formation of acid. Grilling a hamburger involves the Maillard reaction, where amino acids and sugars react to produce a brown color and distinctive flavor. In both cases, new substances are formed with different properties.
