Evaporation is a process that requires energy to occur. Evaporation is an endothermic reaction.

An endothermic reaction is any chemical reaction that requires or absorbs energy (often in the form of heat) from its environment. The activation energy for an endothermic reaction to take place is produced by the absorbed energy. Evaporation is an endothermic reaction. Evaporation is a process in which the molecules that constitutes a liquid absorbs sufficient energy and convert to the gaseous state.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
