Which of the following molecule(s) is (are) polar? co2, ch4, cbr4, or chbr3

CO2 is not polar as in this case the same types of molecules are pulling in the same as well as opposite direction. CH4 is also not polar as there is no imbalance in the charge of the molecules. CBr4 is also not polar because in this case also no imbalance in the molecular charges can be seen. CHBr3 is a bit polar in nature because it has different kind of charges at its opposite ends. S among the all 4 options CHBr3 is polar.

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.
