Polar.
Paper is nonpolar because it is mostly composed of cellulose, which is a nonpolar molecule. Nonpolar substances do not have a separation of charge, meaning they do not have a positive and negative end like polar molecules do.
Air is considered nonpolar because it is mostly made up of nonpolar molecules such as nitrogen (N2) and oxygen (O2). Although water vapor can be present in air and is a polar molecule, the overall composition of air is nonpolar.
