One of the best examples of an endothermic reaction is the chemical process of dissolving table salt in water. If you pour salt into a bowl or container of water, the salt will automatically dissolve on its own. This chemical process will lower the temperature of the water in the contai...Read More

The answer to this is letter C. Sound energy is created when an object vibrates. The sound waves may cause vibrations everywhere. For example, if there is a sound that is made underwater, it will not be surprising if the waves would start to show some pressure. There are times when the so...Read More
