1 LAB SHEET - VISCOSITY OF GLYCERINE Aim: To measure the viscosity of glycerine using Stokes ’ method in which steel balls are allowed to fall through glycerine. Theory: (i) If a body of mass m falls through a viscous fluid‚ it will accelerate until the combination of the viscous force (or drag) FD‚ and the buoyancy force FB balance the gravitational force Fg (= mg) FD + FB = Fg (1) When this equilibrium is reached‚ the body continues to fall‚ but at a constant velocity‚ called the terminal

Electrolyte is a scientific term for salts‚ specifically ions. The term electrolyte means that this ion is electrically-charged and moves to either a negative or positive electrode. Ions that move to the negative which are called cations are positively charged and Ions that move to the positive which are called anions are negatively charged. They can be divided into acids‚ bases‚ and salts‚ because they all give ions when dissolved in water. Electrolytes are present in the human body‚ and the balance

suits me & that’s what I’ll need. I’ve heard a lot negative and positive comments about it; such as “it is a boring class”‚ “not interesting‚ and “a waste of time.” However‚ I like to challenge myself and determine whether if the comments are true or false. “What doesn’t kill you‚ makes you stronger” is my motto‚ and just because other students may not enjoy the class‚ it doesn’t mean that I won’t and fortunately I didn’t. The MGMT 313 class is so far one of my favorite classes. I had teammates in

Moral Absolutes In this paper‚ I will argue that the ethical belief of moral absolutism is false because not all actions are always right and wrong like killing‚ abortion‚ and stealing. Moral absolutism is a belief that there are absolute standards against which moral question can be Judged‚ and that certain actions are always right or wrong‚ regardless of the reasoning behind the certain action. This is the main category of deontological ethics. Deontology bases an act’s morality on its adherence

Intrinsic Viscosity Introduction One of the most precise measurements in polymer science is also the simplest and cheapest. Intrinsic viscosity‚ which is measured from the flow time of a solution through a simple glass capillary‚ has considerable historical importance for establishing the very existence of polymer molecules. It also provides considerable physical insight. In this lab‚ each group will study the intrinsic viscosity of hydroxypropylcellulose‚ a common polymer derived from cellulose--hopefully
