A because a primary source is defined as a first hand account of an event .
Traveling upwards of 200 mph or 320 km/h, and accelerating in a matter of seconds, germs from a cough or sneeze can travel a great distance very quickly.
That is called the<u> variable</u> because it varies/changes in the experiment,

Answer: A is condensation and B is freezing.
The process in which the gas changes to the liquid phase due to the removal of heat is known as condensation. Rains are formed in this way. The water vapour rises. As it raises above it loses heat and then cools down and condenses and comes down as rainfall.
The process in which the liquid changes to a solid on removal of heat is known as freezing. Formation of ice is an example. When the heat is removed at -4 degree Celsius the water freezes to ice.
