1.)Metal expands when heated. Length, surface area and volume will with temperature.
1.)The electrical, magnetic and structural properties of metals can be changed through heat.
2.) The basic building blocks of cheese are milk protein (casein), water, fat, and salt. When heated, the protein molecules break apart and become fluid. Melting, a phase change from a solid to a liquid isn't really happening, the cheese becomes fluid, much like what happens to plastic when it's heated.
2.)We cannot Change the cheese back to it's original state.
3.)Denaturation is what happens when heat is applied to the eggs. Chemically, this is the process by which the chains of amino acids are changed from their original (or native) state. The heat coming from your stove denatures the protein by disrupting some of its bonds that held the molecule into shape.
3.) Cooked eggs and egg dishes can be safely consumed as leftovers if they're initially cooked thoroughly, stored properly, and reheated to an adequate temperature to kill germs and prevent foodborne illness.
4.)If you heat wood, the water boils away first and then the lignin and cellulose (both long-chain organic molecules) will react with oxygen and burn. Even in a vacuum, these molecular chains are too long and tangled to wiggle free into the liquid phase before they reach temperatures high enough to break their bonds.
4.) We cannot change the state of the wood because it has already been heated up and turned into ashes.
5.)Chocolate melts at a relatively low temperature--it literally melts in your mouth. When you heat chocolate, the cocoa butter crystals melt and the chocolate becomes fluid, but if you get the chocolate too hot, it can separate into burned, blackened cocoa particles and pale golden liquid.
5.) Yes we can change the chocolate back to it's original state just put in inside the freezer and let it harden.
6.)As the temperature of the cooking dough rises, the yeast eventually dies, the gluten hardens, and the dough solidifies. Et voilà! Bread!
6.)When you reheat bread, it actually changes the starch molecules back, but this also means they can go stale more quickly afterward. So try to eat your reheated breads within an hour or two. One other common misconception: bread hot out of the oven is actually not ready to be eaten.
7.) When we heat wax, it melts. The state of wax is solid before melting, which on heating converts to liquid wax.
7.)Hence, burning of wax is an irreversible change which cannot be reversed.
8.)Milk is made up of water, fats, carbs, and protein. When you heat it, the water starts to evaporate, and the other components begin to separate. Bringing it to a boil too quickly can burn the sugars and curdle the whey protein.
8.)Milk is irreversible because when we heat it up the water of the milk evaporate thus milk can easily Expire.
9.)As the clay is slowly heated, this water evaporates out of the clay. If the clay is heated too quickly, the water will turn to steam right inside the clay body, expanding with an explosive effect on the pot.
9.)As the clay is slowly heated it cannot be reversed back to it's original state.
