4. Evaporative cooling can be defined as the process of removal of the latent heat from a surface by the evaporation the evaporation of a liquid from there, which results in the reduction of the temperatures. This technique is used for cooling the homes in the dry and hot areas, such as South Carolina. The dry and hot surrounding there makes it easier for the water to evaporate when it passes through the evaporative coolers, making the surrounding air cooler.
Hence, the given statement is true.
5. When the outside temperature is as high as 83 degree Celsius, while the relative humidity is 66%, , it is likely that the sweating will take place, and the water will be evaporated from the skin, making a person feel cooler.
Hence, the given statement is true.

Nerve agent
Explanation:
A nerve agent is a chemical in which on exposure to humans affects the functioning of the nervous system. These chemicals are known to disrupt the process by which messages are transferred to the organs from the nerve. This disruption occurs by blocking the activity of acetylcholinesterase, which is responsible for the catabolism of a neurotransmitter, acetylcholine.
On exposure to a nerve agent, the muscles of the body become paralyzed and early symptoms is production of excess mucous such as in runny nose, pupil constriction and also difficulty in breathing.
These agents are sometimes used in chemical warfare. Examples include sarin, tabun etc.
