states: Solid - In a solid the particles (ions‚ atoms or molecules) are packed closely together. As a result‚ a solid has a stable‚ definite shape‚ and a definite volume. Solids can only change their shape by force‚ as when broken or cut. Liquid - A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. The volume is definite if the temperature and pressure are constant. Gas - A gas is a compressible

sedimentation‚ widely known as Stokes’ law. It states that a particle moving through viscous liquid attains a constant velocity or sedimentation rate. Equation for Stokes’ law Vg = d2 (Pp- P1)/ 18 µ × G Where:- Vg = Sedimentation Velocity d2 = particle Diameter Pp = Particle density P1 = Liquid density G = gravitational acceleration µ = viscosity of liquid Aims:- 1.

subduction zones while the seaward side is locate at oceanic ridges. The explosiveness of the eruption has to do with the flow of the magma and for the landward side the magma originated from the subduction zone. This zone has magma that are of high viscosity‚ they are granitic-andesitic and excrude at 700-9000c‚ have thick short flows that has slaggy surface‚ they cover large distance at slow pace to be specific 10m/hr on flat surface and 100m/hr on slopes. They are said to be explosive because they

the surrounding rocks makes the magma buoyant and it forces its way upward. Cooling and decompression accompanying this ascent cause crystallization as well as volatile exsolution from the magma. A host of processes such as crystal fractionation‚ liquid immiscibility‚ magma mixing and country rock assimilation - together referred to as magmatic differentiation processes – modify the primary magma compositionally leading its complex chemical and physical evolution to derivative magmas.

were not mixed previously. Q-4. How does the diffusion of Honey vary with the diffusion of ink?why? Ink diffuses at a faster rate as compared to honey. This can be explained taking in to account that honey is a more viscous liquid as compared to ink. Therefore the low viscosity of ink allows it to diffuse at a faster rate than honey in a solution. Q-9 Name two gases of air which dissolve in water by diffusion. What is the importance of this process in nature ? Carbon-di-oxide and Oxygen are the
