Answer 1

Hi , here are your answers :

1. Diffusion is the transfer of molecules from a high concentration to low concentration until they are spread out evenly. It is a method of transfer in unicellular and simple multi cellular plants. e.g chlamydomonas and spirogyra .
2. A substance which changes directly from solid state to gaseous state without turning into liquid state by absorbing heat is called a sublime substance. Such a substance in solid state is called sublimate and in gaseous state is called sublime.e.g---naphthalene n iodine , camphor.
3. Boiling : i ) Occurs at a constant temperature , i.e --- the solid's boiling point.ii) Does not cool the surroundings. Evaporation : i ) Occurs at any temperature below boiling point. ii ) Cools the surroundings( like in the case of earthen pots or matkas.)
