It is easier to reverse a physical change.
physical change
Nope. Physical changes are easier to reverse.
Cooking involve chemical reactions.
Cooking carrots is an example of a chemical change. Cooking the carrots breaks down the molecules in the carrots into smaller pieces, making them easier to chew and digest.
Physical
Because its components have changed into something entirely different, so you can't pick out what has gone in. For example, if you mix water and salt, you can not take the salt out of the water because it has reacted with it to be changed into somthing different.

Physical change is preferable because it is easier than chemical method.
It is easier in this case to say why it isn't a physical change. As you cannot turn a roasted marshmallow back into an un-roasted one, A chemical reaction must have occurred. Cooking is normally a chemical change as you cannot un-cook something.

Physical
Physical weathering, such as cracks, creates more surface area for chemical weathering to occur on.
the physical change in the change in food when the enters esophagus is when it has a chemical breakdown in your mouth with a mechanical breakdown the chemical breakdown is when your salivia is making the food moist the mechanical is when you chew the food so it easier for it to enter the esophagus and so the salivia can get it moist then your esophagus uses muscles to push the food down into your stomache

To make people's lives easier and more comfortable
yes
I am not aware of any research to support the assertion that it is easier to remember numbers in reverse.
