and accurate measurements. The objectives in the experiment are to learn how to use laboratory equipment to determine volume‚ mass and temperature. It is also important to learn how to combine units to determine concentration and density in order to measure the density and concentration in different dilutions. Procedure Exercise 1 Length Measurements 1) Gather DVD or CD‚ key‚ spoon and fork. 2) Measure the length of each item in centimeters with one degree of uncertainty‚ record. 3) Measure

Instructions: 1. Why does a hot air balloon float even though it is so heavy? Hot air balloons float because the buoyancy force of the hot air is more that the weight. Buoyancy occurs because the hot air has a lower density than the cooler outside air. This lower density air weighs less than the air it replaces and that difference is the buoyancy. 2. What makes balloons float when they are full of air but not float when they are deflated? Balloons float when they are full of hot air

Effects of Population Density and Noise By: Stephanie Davis Psy/460 Instructor Aaron Graczyk September 2‚ 2013 Effects of Population Density and Noise Density and noise is able to effect people differently‚ a person’s personal space; territory and privacy can be disrupted by other people‚ chronic noise‚ and short-term noise. The different effects can be from an annoying noise to a more strong intrusive and anxiety forming illness. When population density increases the personal space‚ privacy

Lab Report: DRILLING FLUID (MUD) DENSITY Objective: The aim of this experiment is to determine the mud density‚ specific gravity and hydrostatic pressure gradient for water-based-mud‚ WBM (Drilling fluid) using the OFITE mud balance. Theory: Drilling fluids are used during the drilling of boreholes‚ either for oil wells or water boles holes. One of the major functions of a drilling fluid includes providing hydrostatic pressure to prevent formation fluids from entering the wellbore. To ensure
