Answer 1

Both shaking up salad dressing and adding dish soap to water in a sink are physical changes that do not involve the formation of new substances. They can be easily reversed and are not caused by heating or cooling.

Step-by-step explanation:

Both shaking up salad dressing and adding dish soap to water in a sink are physical changes with multiple similarities. Firstly, both changes do not involve the formation of new substances but rather alter the physical state or appearance of the original substances.

Secondly, both changes can be easily reversed by simple methods like stirring the salad dressing or rinsing the dish soap solution in the sink. Lastly, neither change is caused by heating or cooling, as they can occur at any temperature.
