Effects of Force on Confined Fluids essays Experiment # 4- Effects of force on confined fluids Purpose: What effects does a force have on a confined fluid? Hypothesis: I think the force will effect how much a confined fluid is able pressurize. 1) In your book draw a table like table 2-6 2) Calculate the force with which gravity will pull on each of the masses listed in table 2-6, and note these in the appropriate column. (Recall that force is measured in newtons. The force of gravity on a 1kg mass is 10n) 3) Set up the apparatus as shown. Withdraw the piston until there is exactly 50 ml of air in the syringe into the hole in the stopper. It should fit closely making an airtight seal. 4) Place one 1kg mass on the platform, and record, in the appropriate column of the table, the volume occupied by the fluid. Repeat with two 1kg masses on the platform, then with three masses, then with four. 5) Remove all the masses and record the volume of fluid in the syringe. 6) Repeat steps 3 to 5, starting with 50 ml of water in the syringe. Be sure to remove all the air from the syringe, using the method shown on page 64. 3)(a) The gas then decompressed, because nothing was keeping it packed. (b) Nothing had happened because a liquid cant be compressed unless using an extreme amount of pressure. 4)(a) Gas Particles move much faster than liquids particles do. Gas particles are spread out and out of control. Liquid particles are crammed together, but still a lot of movement. (B) There are fewer particles in gas, when applying pressure they start to move closer together, until crammed together. (C) Because liquid particles are close which makes them hard to compress anymore, then they already are. Liquid can be compressed whe ...
