Scientists observe patterns in how molecules interact with each other. At the same temperature, for example, liquids have more attraction between particles than gases do. Water (H2O) is a liquid at room temperature, while carbon dioxide (CO2) is a gas at room temperature. Why? Choose the two statements that apply. A. Nonpolar molecules only attract polar molecules.
B. Polar molecules attract each other more than nonpolar molecules do.
C. Water molecules are polar. Carbon dioxide molecules are not.
D. Carbon dioxide molecules do not have polar bonds. Water molecules do.
