temperature usually increase when water condenses. which behavior of water is most directly responsible for this phenomenon?
Yuki888 [10]

Answer:

the release of heat by the formation of hydrogen bonds.

Explanation:

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

Condensation can be defined as a process which typically involves the change in the physical state of matter from the gaseous phase into a liquid phase i.e water changing from gas (vapor in the air) into a liquid form.

Temperature usually increase when water condenses. This phenomenon is as a result of the release of heat (exothermic reaction) by the formation of hydrogen bonds in water i.e hydrogen-hydrogen bond in water molecules formed by the chemical elements; oxygen and hydrogen.
