Then a sample tube filled with two mercury plugs was obtained from the instructor. With a ruler‚ the distance between the two mercury plugs was recorded. Using small rubber bands‚ the sample tube was strapped to the ruler‚ which was then attached to the bottom of thermometer. A cork was attached onto the top of the thermometer‚ and

1-1 Chapter 1 INTRODUCTION AND BASIC CONCEPTS Thermodynamics 1-1C Classical thermodynamics is based on experimental observations whereas statistical thermodynamics is based on the average behavior of large groups of particles. 1-2C On a downhill road the potential energy of the bicyclist is being converted to kinetic energy‚ and thus the bicyclist picks up speed. There is no creation of energy‚ and thus no violation of the conservation of energy principle. 1-3C There is no truth to his claim

Mercury and Other Pollutants Like other fossil fuels‚ coal-burning boilers emit dangerous pollutants including mercury. One fourth of the dangerous nitrogen oxides produced in the U.S. each year come from coal-burning industrial boilers. Coal burning also produces two-thirds of the sulfur dioxide and one-third

phenomena such as meniscus‚ surface tension and capillary action. Mercury in a glass flask is a good example of the effects of the ratio between cohesive and adhesive forces. Because of its high cohesion and low adhesion to the glass‚ mercury does not spread out to cover the bottom of the flask ‚ and if enough is placed in the flask to cover the bottom‚ it exhibits a strongly convex meniscus‚ where the meniscus of water is concave . Mercury will not wet the glass‚ unlike water and many other liquids
