Difference between epidermis and cork?

Epidermis:1. Single layered group of cells that cover plant leaves, flowers, root and stem.    2. It is permeable in nature. Protect against water loss, gas exchange and absorb water and minerals.

Cork:1. The cork is a water proof protective layer (bark) present on the cork trees. It consist of dead cells. 2. Impermeable in nature.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
