Molar Mass of a Volatile Liquid There are several ways to find the molar mass of a substance. One way‚ if the substance is a gas‚ is to use the Ideal Gas Equation to find molar mass. The standard equation reads PV=nRT where “n” is the number of moles present‚ “P” is the pressure (which is obtained by reading the barometric pressure of the room with the class barometer)‚ “V” is the volume of the gas‚ “R” is the universal constant‚ and “T” is the temperature of the gas. The experiment’s objective

radius: ((2.2)^2)/(2*0.5*(2.2^2)*(3+(.5*15))/(3*9.8))/0.25 Sphere on Incline: A solid sphere of uniform density starts from rest and rolls without slipping a distance of d = 3.7 m down a θ = 33° incline. The sphere has a mass M = 4.2 kg and a radius R = 0.28 m. For this one‚ you have to do part © first… and don’t forget that ur working with a sphere‚ so u gotta look up the moment of inertia (I) in order to get the correct answer… a) Of the total kinetic energy

Phenomenology and the Catholic Eucharistic Mass G. Wilson In the study of communications‚ reaching a common consensus on how to apply a shared and common understanding of communications seems to be a near impossible task. After being introduced to the seven traditions of communications by Craig in his essay “Communication Theory as a Field”‚ I choose to explore the tradition he categorizes as Phenomenology. My initial understanding on the study of communications were quite limited to the transmission

For other uses‚ see E=MC2 (disambiguation). 3-meter-tall sculpture of Einstein’s 1905 E = mc2 formula at the 2006 Walk of Ideas‚ Berlin‚ GermanyIn physics‚ mass–energy equivalence is the concept that the mass of a body is a measure of its energy content. In this concept the total internal energy E of a body at rest is equal to the product of its rest mass m and a suitable conversion

India Arulprasath.kvit01@gmail.com; Abstract This paper deals with the discussion of mass and energy in light. Light consist of very less amount of mass that it could not be measured. This paper is based on the concept that when the mass of light is increased it can move the objects. So‚ the light with increased mass can be used in many applications in practical life such as producing electricity. Increase of mass in light‚ leads to much more attraction in the academic sphere. It is necessary to take

1. Define production. What are the factors of production? Define production: Production means the creation of Utility. Through production inputs are converted into output which can satisfy or meet wants or demands. So production is a process of transforming inputs into useable outputs. Utilities are created in three forms such as (i) Changing the form (ii) changing time and (iii) changing place. Example: Wood in a forest generally has no utility to a consumer but cutting the wood‚ changing

Example problems involving collisions 1) On a horizontal frictionless surface a puck of mass m initially at speed u collides head-on (without rotation) with a stationary puck of mass M. Find the velocities of both puck after the collision if: i) the collision is fully elastic ii) the collision if fully inelastic. i) momentum: kinetic energy: mu = mv+MV (+ve in direction of initial u) 1 /2 m u2 = 1/2 m v2 + 1/2 M V2 2 eqns in 2 unknowns: V = (u - v) m/M substitute in K eqn: u2 = v2 + (M/m) V2 =

Conservation of Mass Lab Introduction- Problem: To validate the law of conservation of mass and to examine what happens when one Alka- Seltzer tablet is combined with water. Hypothesis: If the Alka-Seltzer tablet is combined with water‚ then Co2 will be produced because when mixing the two compounds‚ a chemical reaction will occur. Materials: -Alka-Seltzer tablet -Balance (Grams) -Balloon -Flask (125 mL) -Water -File -Forceps -Massing tray Procedure: 1. Mass the Alka-Seltzer
