What changes from blue to brown to orange when heated with surgar?
Sugar. When heated, sugar undergoes a series of chemical reactions called caramelization, which changes its color from white to light brown to dark brown to orange.
When paper turns yellow brown upon exposure to sunlight what type of change has taken place a chemical or physical change?
A chemical change has taken place. The exposure to sunlight causes the paper to undergo a chemical reaction, breaking down the molecules in the paper and causing the color change to occur.
Is changing color of apple a chemical or physical change?
Changing the color of an apple is a chemical change because it involves a chemical reaction that alters the molecular structure of the apple's pigments, such as when the apple oxidizes and turns brown.
Is the reddish-brown metal a physical or chemical change?
Neither. Hash Brown refers to a style of cooking potatoes in which the potatoes are shredded raw, flattened into about a 1/2" thickness and then browned on both sides by pan frying either on a griddle or in a frying pan using a small amount of fat. When the potatoes are first peeled and sliced however, they can start to turn brown if exposed to oxygen and not cooked due to enzymatic browning (a chemical reaction). When the hash browns are fried, the exterior will turn brown through a chemical process known as the "Maillard Reaction."
Is a piece of avocado turning brown a chemical change or a physical change?
The browning of an avocado is a chemical change. This process, known as oxidation, occurs when enzymes in the avocado interact with oxygen in the air, causing a change in the chemical composition of the fruit.
Are Sliced apples turning brown an example of chemical or physical property?
Sliced apples turning brown is an example of a chemical property, specifically oxidation. When the apple cells are exposed to oxygen, enzymes in the apple catalyze a reaction that changes the chemical composition of the apple's surface, causing it to turn brown.
A sliced apple turning brown is exhibiting the ability to react with oxygen a physical property?
The sliced apple turning brown is a chemical change, not a physical property. It is a result of a chemical reaction between the compounds in the apple and oxygen in the air, leading to the formation of new compounds that give the apple its brown color.

Is this a physical or chemical change when butter granulated sugar brown sugar and vanilla are mixed together?
so i think its a chemical change because when mixing all these ingreedients together, one substance is being dissolved into another, which the property of solubility. Since solubility is a chemical propery then i would assume chemical. Also a physical property is a reverible change such as ice melting or water freezing, once vanilla and sugar are mixed together, then i dont think that you can separate them again therefore it couldn't be a physcial property. Hope this helps!
What is the physical property of a brick?
A bricks one physical property of a brick is the brick's brown color and rough feeling.
Is changing color of apple a chemical or physical change?
Changing the color of an apple is a chemical change because it involves a chemical reaction that alters the molecular structure of the apple's pigments, such as when the apple oxidizes and turns brown.
When botanic acid is heated or stirred does a chemical reaction occur?
It will split in a brown stinky gas and a white fluid
Is the ability of a substance to reflect light a chemical property why?
Some compounds undergo photo(light)degradation or photolysis when they are exposed to light. Some chemicals are stored in brown bottles due to this reason.
