Ответ:
An endothermic reaction is the opposite. This is when a reaction starts colder and ends up hotter, taking in energy from start to finish. In an endothermic reaction, the system gains heat as the surroundings cool down. In an exothermic reaction, the system loses heat as the surroundings heat up.
Ответ:
Heat just like the sound is a form of kinetic energy. Molecules that have a high temperature have more energy, thus they can vibrate faster and when the molecules vibrate faster, sound waves travel more quickly.
