    transferred to another section. Which are evaporation‚ radiationconvection and radiation ( Jeng‚ 1998 ). Evaporation is when liquid changes into a vapor at a temperature below the boiling point. Evaporation takes place at the surface of a liquid‚ where molecules with the highest kinetic energy are able to escape. When this happens the average kinetic energy of the liquids is lowered and its temperature decreases ( The American Heritage‚ 2015 ). Convection is the transfer of heat by the circulation of

    Nervous System The nervous system is the part of an animal’s body that coordinates the voluntary and involuntary actions of the animal and transmits signals between different parts of its body. In most types of animals it consists of two main parts‚ the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord. The PNS consists mainly of nerves‚ which are long fibers that connect the CNS to every other part of the body. The PNS includes motor
