A reversible process is defined as a process in which the system and surroundings can be returned to the original conditions from the final state without producing any changes in the thermodynamics properties of the universe, if the process is reversed.
The reversible process is the ideal process which never occurs, while the irreversible process is the natural process that is commonly found in nature. ... This is an irreversible process. Whereas when water evaporates, it can also be condensed in the form of rains.
Irreversible processes are characterized by the flow of fluids with friction, and sliding friction between any two matters. An example of an irreversible process is electric current flow through a conductor with a resistance. An example of an irreversible process is magnetization or polarization with hysteresis.

Leaves are vital to the survival of plants. They help plants in a variety of ways, including producing food and oxygen through photosynthesis, balancing water loss, regulating gas exchange, and transporting the products of photosynthesis.
A leaf has two main parts:
(1) Petiole- the stalk that supports a leaf in a plant and attaches the leaf blade to the stem.
(2) Lamina- the green flat part of a leaf that is specialized for photosynthesis. The lamina contains the following parts:
(i) Veins- the lines on the green flat part in a leaf that provide support for the leaf and transport both water and food.
(ii) Midrib- The central, thick, linear vein that runs along the length of a leaf is called midrib.

Malleability is a property of material by which in can be beaten to form its thin sheets. Most of the metals are malleable. Examples of malleable metals are zinc, iron, aluminum, copper, gold, silver, and lead. silver and gold are highly malleable. Ductility has to do with tensile stress, whereas malleability deals with compressive stress. Materials such as lead are very malleable and can be hammered into shape with little chance of fracturing, but they are not ductile and will easily fracture if pulled from two opposite directions.

The process of evaporation followed by condensation causes the formation of clouds. Water present on the earth’s surface gets evaporated due to sunlight, and then rises up in the atmosphere. On reaching a certain height, water vapour present in air condenses to form tiny droplets of water. These water droplets collect to form clouds that float in air.

Evaporation is the process of liquid turning into vapour. It is exactly the opposite process of condensation. When water changes from liquid state to atmospheric vapour state to enter the water cycle, it becomes a primary pathway for evaporation.
