Our students are confused over the composition of comets. Some books state they are
mainly made up of frozen gases (methane, ammonia, carbon dioxide, carbon
monoxide), and bits of dust. Other books refer to frozen ices. The students know that
frozen CO2 is dry ice. Is there any frozen water in comets?
