When using charles's law, why should the temperature units always be kelvin?

Explanation:

On the basis of Charle's law, the volume of a given gas mass changes straightforwardly with the absolute temperature of the gas when the pressure is maintained the same. The absolute temperature is determined with the Kelvin scale. There is a need to use the Kelvin scale as zero on the Kelvin scale relates to a complete stoppage of molecular movement.  

In the gas law problems, the Kelvin scale is used as the volume and pressure of a gas relies upon the motion or kinetic energy of the particles. The Kelvin scale is equivalent to the kinetic energy of the particles, that is, 0 Kelvin signifies 0 kinetic energy, and on the other hand, 0 degree Celsius is basically the freezing point of water.  

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.

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.
