Energy convention: Convection is the motion of a fluid driven by temperature differences across that fluid. When a fluid is heated, the region in closest contact with the heat source becomes less dense due to increased kinetic energy in the particles. Convection is one of the fundamental ways that heat is transferred
Answer:
kinetic energy is a energy of motion. At a given temperature, individual particles of a substance have a range of kinetic energies. The motion of particles theoretically ceases at absolute zero.
Answer:
True
Explanation:
Sewage contains many substances in it like suspended solids, organic and inorganic impurities, nutrients, saprotrophic and disease causing bacteria and other microbes. Hence it is said to be a complex mixture.
