Answer:
According to the study, urban heat islands, created from pavement and buildings in big coastal cities like Houston, cause warm air to rise and interact with sea breezes to create heavier and more frequent rainfall in and downwind of the cities.
If the electronegativity difference is less than 1.6 or when the difference is 1.6 - 2.0 and it only involves nonmetal, then the molecule contains a covalent bond.
A. HF: 4.0 - 2.1 = 1.9 (Covalent)
B. LiCl: 3.16 - 0.96 = 2.2 (Non-covalent)
C. CN-: 3.04 - 2.65 = 0.39 (Covalent)
D. MgO: 3.44 - 1.31 = 2.13 (Non-covalent)
Answer:
C
Explanation:
C. It is considered a cooling process and it lowers the average kinetic energy of the liquid because the higher energy molecules turn to vapor.
Moreso, evaporation does not increase the average kinetic energy because it is a surface phenomenon. Also, as molecules excape at a fast moving rate, the left over molecules have a lower kinetic energy and this consequently decreases the temperature of the liquid.
When molecules absorbs heat, the evaporate and this phenomental process provides cooling in the system
