Question

The uniformly sweet taste of coffee or tea is due to
A. Spreading
B. Permeability
C. Distribution
D. Diffusion

Answer 1

Hint: Due to the presence of a component called caffeine makes the tea or coffee taste bitter. Tea and coffee are the common beverages consumed by people. The quinine present in coffee makes it better and it is also present in tonic water. This process usually occurs in liquids and gases.

Complete answer: The uniformly sweet taste of coffee or tea is due to the process called diffusion. In diffusion the movement of solvent molecules take place from high concentration to a low concentration area.
a) The word spreading refers to the spreading of molecules in a solvent from a region of high concentration to a low concentration region. The spreading of particles led to the uniform distribution throughout the given volume.
b) Permeability refers to the allowance of passage of materials through the semipermeable membrane which act as a repellent to large molecules. The hydrophobic center of the cell gives the membrane to cause permeability which results in restriction of molecules from passing throughout the membrane.
c) The word distribution refers to the spread of the molecules over an area. It can also be referred to as dividing the quantity and distributing over an area.
Therefore, option D is the correct answer.

Note: The most consumed beverage in the world is tea and has around 3000 different types of tea and is also considered as the favorite drink of most of the people in the world. In India, the southern parts are famous for coffee production and the eastern parts are famous for tea production.
