<span>Because there is a permanent dipole between the Br and Cl atom. The Cl atom has a higher electronegativity, so it will tend to pull the "shared" electrons formed in the bond to its pole, creating a permanent dipole and partial electron deficiency on the bromine atom.</span>
Answer:
Change occur in heat energy.
Explanation:
Change occur in the heat energy of molecules during condensation process. The molecules of gas releases its heat energy and converted into liquid state. With this heat energy, they are active and escape from each other but when the heat energy is removed from them, the attractive forces between these gas molecules are formed which convert them into liquid state so change in heat energy occur in the condensation process.
The heat energy that causes most of the water evaporate on the surface of the Earth is the Sun. Which provides earth most of the thermal energy into the hydro-thermodynamic system on Earth.
{{Sun}}
