We use energy every day, and energy comes in different forms. Chemical energy is energy that is stored in chemicals, such as sugar and gasoline. As chemical energy is stored energy, it is a type of potential energy, which is energy stored in objects due to their location.
An example of a finger cot. A finger cot (also finger frock or finger stall, informally finger condom) is a medical supply used to cover one or more fingers in situations where a full glove is unnecessary. Like medical and rubber gloves, finger cots may be made from a variety of water-tight materials including latex, nitrile rubber, and vinyl. A toe protector or toe cap is very similar, but shorter and of greater diameter.
Spoon-shaped or spooning fingernails refers to a concavity in the fingernail itself, resulting in a depression in the nail that gives an appearance of a spoon shape to the entire nail. This growth disturbance in the nail is medically known as koilonychia. The spooning is typically such that a water droplet may be placed and held in the depression within the nail. This pattern can sometimes be seen in normal infants, but it disappears as the child ages.
