The energy that a body possesses due to its motion is called kinetic energy. It is given by the formula: where is the mass of the object and is its velocity. Potential energy, on the other hand, is the energy stored due to an object's position or configuration.
Thus, the correct answer is Kinetic Energy.

Rusting is a chemical reaction in which iron reacts with oxygen and water to form iron oxide (Fe₂O₃·xH₂O), commonly known as rust. Since rust formation involves the addition of oxygen from the environment, the mass of the iron object increases due to the added oxygen.
Thus, the correct answer is Increases.

Phosphorus is primarily extracted from bone ash and phosphate rocks. Bone ash, which is derived from the calcination of animal bones, contains a high percentage of calcium phosphate, which serves as a significant source of phosphorus.
Thus, the correct answer is Bone ash.

In semiconductors, the electrical conductivity increases as the temperature rises. This is because more electrons gain enough energy to jump from the valence band to the conduction band, leading to an increase in charge carriers. In contrast, conductors experience a decrease in conductivity with an increase in temperature due to the scattering of charge carriers.
Thus, the correct answer is Semiconductor.
