Physical change: it's just beginning to freeze. Also, it's chemical composition stays the same.

it depends on how much gravy granules you put in when it was hot. the thicker the gravy was when it was hot determines the solidity of the gravy when its cold. it will never be completely solid but stodgy.
Gravy is a mixture of water, fat, flour, and seasonings. The fat and flour form a roux, which thickens the liquid (water or broth) to create the smooth texture of gravy. Seasonings are added for flavor.
Brown gravy is typically acidic due to ingredients like vinegar or lemon juice that are used to enhance flavor.
One way to separate fats from a gelatinous mixture is by chilling the mixture in the refrigerator. The fats will solidify and rise to the surface, making it easier to skim them off. Another method is to use a gravy separator, which allows you to pour off the liquid while leaving the fats behind.
Because making gravy merely involves dissolving the powder in water, it is classified as a physical change. This is due to the fact that neither the powder, nor the water are undergoing and change in chemical properties.
Yes, you can freeze gravy for later use. Make sure to store it in an airtight container and thaw it in the refrigerator before reheating.

In a chemical change, the atoms or molecules are changed in that they become something else, like if something burns, while a physical change is if it changes state (e.g. gravy is like a jelly when it's cold so if you warm it up, it turns back into a liquid (physical change), but if you cook it too long it burns (chemical). That's how I remember it, anyway.
I have kept an open #10 can of Signature brand sausage gravy in the refrigerator, uncovered, for a week. I havent had any food poisoning.
Yes, you can freeze homemade gravy for later use. Just make sure to cool it completely before transferring it to a freezer-safe container. When ready to use, thaw it in the refrigerator and reheat it on the stove or in the microwave.
It's both. The peas, carrots, etc all swirl about, that's physical. The water weakens the bonds on the beef as it heats up, and some of the particles come out of the beef and go into solution, along with the carrots, and some flour and salt and make a nice gravy, and some processes during cooking are chemical.
Their are actually 9 types of gravy. Theyinclude: Chocolate Gravy Egg Gravy Giblet Gravy Mushroom Gravy Onion Gravy Red-Eye Gravy Vegetable Gravy Cream Gravy Brown Gravy
To prevent gravy from freezing when storing it, make sure it is completely cooled before placing it in an airtight container. Leave some space at the top of the container for expansion, and store it in the refrigerator rather than the freezer. Stir the gravy occasionally while it cools to prevent a skin from forming on top.
Bacteria can and does grow just about everywhere, from the hot thermal vents at the bottom of the ocean to ice caves. Gravy is actually a pretty good medium for growing bacteria - there is a fair amount of available water, gravy is usually not stored in an air-tight container so there is plenty of oxygen for the aerobic bacteria, and gravy has a relatively abundant supply of carbohydrates, proteins and fats.
It is not advisable to store hot gravy in Rubbermaid storage bowls immediately after cooking. Pouring hot liquids into plastic containers can warp the material or cause it to leach chemicals. It's best to let the gravy cool to room temperature before transferring it to the storage bowl. Once cooled, it can be safely stored in these containers in the refrigerator.
Gravy without potatoes is just that... Nothing but gravy.
