What are fragments of dust, soil, salt, smoke and ash upon which water vapor condenses to make clouds this is science btw

Particulate matter

Explanation:

The particulate matters are defined as the aerosol particles that are found to be present freely in the atmosphere. They are the mixture of dust, soil, salt, liquid drops, smoke and ashes. They can be formed both naturally and from the anthropogenic activities. These smaller particles present in the water vapor undergoes condensation, forming liquid and ice on the surfaces of dust particles present in the atmosphere. With more frequent condensation of water vapor, results in the formation of clouds.

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.
