Can bonds stretch when heated
WebAs can be seen by the diagram below, when thermosets are cured or hardened, cross-links are formed between adjacent molecules, resulting in a complex, interconnected network. These cross bonds prevent the individual chains from slipping, thus preventing plastic flow when heat is added. WebA fast moving molecule (the cue ball) strikes a lattice of slow moving ice or water molecules. The cue ball rapidly decelerates (is cooled) as the rest of the balls jumble around the board in a liquid or gas-like state. Answer 3: Water absorbs heat by vibrating and rotating. The vibrations can be the stretching or bending of the chemical bonds ...

Webrubber molecules in a crystal. When molecules, not just rubber molecules, but any molecules, form crystals, they give off heat. This is why the rubber band feels hot when its stretched. When you let go of the rubber band, the polymer molecules break out of those crystals. Whenever molecules break out of crystals, they absorb heat. Webweak. This cheese may not melt or stretch when baked because the S-S bonds do not break. If the serum proteins are heated in the absence of casein, they also form aggre …

WebThe active site of the enzyme can provide a microenvironment with a different pH that facilitates the reaction. Binding of the substrate to the active site can stretch bonds in the substrate that need to be broken. The active site can provide heat from the environment that raises the energy content of the substrate.
