Two beakers contain clear, colorless liquids. when the contents of the beakers are mixed a white solid is formed. is this an example of a chemical or a physical change?

is a chemical change

Explanation:

chemical change occur when some substances are transformed  into different substances, with different nature and properties, in this case when both liquids are mixed a whithe solid is formed.  this is an example of change of state of the liquids reactants to the solid product, which has properties and characteristics different from that of the initial liquids of the mixture,

physical change: they are all those in which no substance is transformed into a different one.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
