DO VOLCANOES HAVE A DESTRUCTIVE POWER AS WELL AS POTENTIAL BENEFIT Volcanoes are usually depicted as towering mountains missing a chunk out of the top from which steam‚ ash and lava spew forth. In reality‚ a volcano is any spot on the surface of the Earth where lava flows. Magma finds its way upwards along fissures or cracks in the planet ’s crust and bursts out onto the surface‚ resulting in a volcano. Magma that flows out of a volcano is called lava. If it comes out of the volcano in an explosive

eggs and larvae. Cones: A cone is a three-dimensional geometric shape that tapers smoothly from a flat‚ usually circular base to a point called the apex or vertex. Volcanoes form cones‚ the steepness and height of which depends on the runniness (viscosity) of the lava. Fast‚ runny lava forms flatter cones; thick‚ viscous lava forms steep-sided cones.

transported to its users.” (NOAA 2012) Based on information from NOAA‚ oil can be categorized into four different types of oil ranging from very light to heavy oils‚ which are different depending on each of their viscosity‚ volatility‚ and toxicity. Oil’s resistance to flow is known as viscosity. Volatility is described on how fast the oil evaporates into the air. How poisonous the oil is to the organisms and humans is referred to as toxicity. The four different types of oil can affect the environment

The catalytic cracking mesuaferrea seed oil to biofuel was studied in a microwave reactor with selected catalysts at .500-600˚C The thermo-physical and chemical properties of straight mesuaferrea oil were determined. The flash point‚ kinematic viscosity‚ and density of the straight mesuaferrea oil were found to be much higher than diesel‚ though the calorific value was found to be lower. The variation in thermo-physical and chemical properties of various blends of straight mesuaferrea oil and diesel

Hydrogel based controlled release formulations: Designing considerations‚ characterization techniques and applications. Abstract Hydrogels have evolved over the last decade as materials of choice in varied biomedical applications. This is associated with the inherent biocompatible nature of the hydrogels. The modulation of the properties of the hydrogels is easily possible due to the availability of polymers of varied chemistry and physical properties. This review discusses the pharmaceutical

recorded data points of the experiment‚ the experimental and theoretical heat transfer coefficients can be found‚ and those are used to understand the natural convection of the sphere. The mass‚ specific heat of brass‚ diameter‚ area‚ and kinematic viscosity‚ are all known values and used to calculate the Nusselt number‚ Raleigh number‚ and the heat transfer coefficient at a certain point. The following equations were used to calculate the results in the experiment: y = a1X + a0 a_1=(ΣxiΣyi-nΣxiyi)/((Σxi)^2-nΣxi^2
