Aim: To find the mass in grams (m) of a paperclip. Apparatus: Procedure: 1. Using a piece of string‚ the external circumference(C) of the small test tube was found and was then used to find A ‚ the cross sectional area of the small test tube A=C24π . 2. The beaker was placed under the test tube after it was clamped on the retort stand to collect excess water. The large test tube was filled with water. After which‚ the small test tube which had a fitted scale was placed inside to float

rate of heat transfer to the surroundings. It is possible for an object to have a very high temperature but contain very little heat and vice versa (physics 312). When a hot body is mixed with the cold body‚ the hot body cools down and the cold body warms up until the mixture as a whole comes to a common temperature‚ that is‚ in thermal equilibrium. By mixing hot and cold substances and measuring the change in temperature‚ the thermal characteristics of the substance can be determined. The purpose

Science in the Big City: Exploring Career Opportunities in the Natural and Physical Sciences New York City May 13-18‚ 2014 Students in the Natural Sciences at the University of Houston-Downtown are generally accomplished and motivated students with strong interests in science. However‚ students typically have a very limited perception of the science careers available to them outside of medicine. To educate students as to the array of potential careers available in the sciences (not medicine)

ABSTRACT: The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment‚ one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2‚ which is consistent with the accepted value of 9.8m/s^2. In the

Experiment-5 Thermal physics is the combined study of thermodynamics‚ statistical mechanics‚ and kinetic theory. This practical is done to measure the temperature drop of water over a period of time (30 minutes). Research question- What is the rate of temperature change over a period of 30 minutes? Independent variable- time Dependent variable- the temperature of water Controlled variables- the amount of water in the calorimeter - The stop watch

Measurement of the distance‚ the thickness and the radius of curvature Purpose : To learn how to use vernier caliper‚ micrometer and spherometer to measure internal and external diameters of a pipe‚the thickness of a copper rods‚ and the radius of curvature of spherical lenses. 1) Vernier caliper: As shown in Fig. 1 the main fixed scale in the vernier caliper has 1 mm gradations while th sliding scale (vernier scale) has 0.05 mm gradations. The smallest division of vernier scale is called
