Flammable liquid

Large quantities can be found in bulk storage containers or transport vehicles on any street or interstate. Gasoline is a hydrocarbon fuel with a very low flash point and is easily ignitable. Fires involving gasoline are unique because they cannot be extinguished by water alone. “The ability of water without additives (foaming agents) to put out a fire is limited on low-flash-point flammable liquids” (Cote & Bugbee, 1988, p.168). The reason that water alone cannot be used on flammable liquid fires with low flash points is that the water will probably sink to the bottom of the fuel. If the fire was contained in a tank, the water would sink and cause the fuel to rise in the container and overflow. Cote & Bugbee (1988) also tell us that “in case of a spill fire, water probably will cause the fire to spread”…

I was able to identify all the liquids in our sludge but only about half of our solids mainly because we only started working at a good pace towards the very final days of sludge. We didn’t identify any gases because there wasn’t any in our sludge. We only had three liquids in our sludge. We were able to get at least 10 ML. of liquid A and Liquid B. We had about 6 ML. of liquid C but on day #18, Monday, May 20, all our our liquid C was gone. I’m not exactly sure what happened like if the test…

Lab Report: Density and Viscosity Problem: What is the effect of density on the viscosity of a substance? Hypothesis: Density will affect the viscosity of a liquid. The order of the liquids from most dense to least dense is: syrup, detergent, water, oil Background: Density and viscosity are closey related in which they both affect one and other. Denisty has many factors like weight, mass, and volume. To work cohesivly there are different things we must pay attention to. Density is how closley…

Introduction A blender generally consists of a plastic or glass pitcher that locks into a large base. Some of blenders are made of stainless steel. The lid of the pitcher has a seal that prevents the food or liquid from splashing out while the blender is in motion. The motor has varying speeds that turn either two or four sharp, stainless steel blades. The blades slice, crush and blend the contents of the pitcher..Blender is a must have kitchen equipment for nearly all families today, especially…

AIM OF THE PRACTICAL The aim of this practical was to investigate the reality or the accuracy of the formula for the resultant force on and the position of the centre of pressure on a vertical rectangular surface. SKETCH OF APPARATUS Counterbalance weight Balance pan(with 20g mass piece) Flat/curved surface(as shown below) Water Beaker Mass pieces(20g each) SUMMARY OF THEORY Hydrostatic force is the force exerted by the…

3.1.3 Pump A pump is a gadget that moves liquids (fluids or gasses), or once in a while slurries, by mechanical activity. Pumps can be characterized into three noteworthy gatherings as indicated by the technique they use to move the liquid: direct lift, dislodging, and gravity pumps. Pumps work by some component (regularly responding or turning), and expend vitality to perform mechanical work by moving the liquid. Pumps work by means of numerous vitality sources, including manual…

provides the thermal energy for the thermal decomposition and subsequent recombination of the constituent species followed by sintering and recrystallization of the clusters of crystallites results in coherent film. The chemical solution is atomized into a spray of fine droplets with the help of carrier gas. As compared to other film deposition techniques, pyrolytic deposition of thin films is relatively inexpensive in terms of equipment cost. In a properly designed reactor and after suitable…

The main purpose of this experiment is to purify an impure solid by the technique of recrystallization. This technique involves several steps, selecting an ideal solvent, dissolving the compound in a minimum amount of boiling hot solvent, filtering insoluble impurities while the solution is hot; crystallizing the purified compound, and isolate the pure compound by vacuum filtration . The unknown used in the experiment was #4, which were white crystals. In order to determine the ideal solvent…

sugar in the sugar column and a 1 teaspoon of salt in the salt column. 12. Add a different colour of food colouring to this row. 13. In the last row add a tablespoon of tap water to the blocks in both the sugar and salt columns. 14. Place the ice tray in the freezer. 15. Set an alarm for 30 minutes. 16. After 30 minutes check how much the solution has frozen with a tooth pick. 17. Write down your observations. 18. Place the ice tray back in the freezer. 19. Repeat Steps 16 to 19 until all cubes…

During the winter in some places it can get very cold, and it might even snow. People put many different things on the ground to make the snow melt, but which one really melts the snow the fastest? Does ice melt fastest with salt, sugar, or sand. There are many things that can solve this question. In order to see if something is soluble it needs to be mixed with a solvent (water). To be soluble means that it is able to be dissolved. There are three different possibilities that can happen.…
