Explain why the process of dissolution can be exothermic or endothermic (heat of solution) with different solutes

The process of dissolving is exothermic when more energy is released when water molecules “bond” to the solute than is used to pull the solute apart. Because more energy is released than is used, the molecules of the solution move faster, making the temperature increase.

Project the image Endothermic Dissolving.

The process of dissolving is endothermic when less energy is released when water molecules “bond” to the solute than is used to pull the solute apart. Because less energy is released than is used, the molecules of the solution move more slowly, making the temperature decrease.

Because of Iceland’s location.
It’s located along the mid-atlantic ridge, which is a divergent plate boundary. This means that two tectonic plates are sliding away from each other, which opens up the seafloor and allows lava to flow upwards, which creates volcanoes.
