2.020 g of a salt A is dissolved in 25-mL of water contained in a calorimeter. What is if the mass of empty calorimeter is 9.969 g, the mass of the calorimeter + solution is 36.086 g, the temperature of the water is 19.71 °C and the temperature of the solution is 34.20 °C? Assume that the specific heat (cs) for the solution is 4.184 J/g. K. Answer should follow the rules for significant figures and give the proper units. ​

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.
