Diffusion - Class 9, Matter in our Surroundings, Chemistry Diffusion Krishna April 5, 2021 Class 9 Comments Advertisement "The intermixing of particles of two different matter by their own is called Diffusion. Recently, French scientists discovered that mixing water, a mineral called olivine, and aluminum oxide in a DAC and subjecting the mixture to extreme pressure for 24 hours creates hydrogen gas [3,4]. Relative density of a substance is the ratio of its density to the density of water. The characteristics of the particles of matter are: (1) Particles have intermolecular space.
Carbon monoxide levels in blood may not induce cardiovascular disorders. She assumed that A is a metal and B is a non-metal. What are the physical states of matter? The difference in pressure helps in the movement of air. Air moves from a region of higher air pressure to the region of lower air pressure. Thrust and pressure are often co-related.
