process by which a stated measure such as the volume of a container is checked for accuracy. In general‚ measurements of mass can be determined more precisely and accurately than measurements of volume. Therefore‚ the mass of the liquid contained or dispensed by the glassware will be measured and the corresponding volume calculated using the density of the liquid. However‚ a relatively small change in temperature causes a change in the liquid’s volume and thus its density. 1.2 To Contain vs

expand when the heat is added. When the temperature increases‚ the volume of the gas increases. During the winter season‚ a football inflates inside gradually‚ and as soon as it is taken outdoor‚ it starts shrinking slightly. When the temperature inside the house (room temperature) is warm and hot‚ the football inflates (the volume increases)‚ as the temperature increases. When it is taken outside‚ the temperature goes down‚ and the volume of the football starts to decrease. Boyle’s Law describes how

between them also increase which results in the increase of the volumes of matters. All expansions occurs in volume of the substance however‚ sometimes some of the dimensions of them expand more with respect to others. In this case we neglect the less expanded ones and assume expansion like linear expansion in long materials. Moreover‚ we take the expansion of plate as area expansion and finally we take the expansion in three dimensions as volume expansion. thermal expansion Inverse of the expansion

a cube is a three-dimensional solid object bounded by six square faces‚ facets or sides‚ with three meeting at each vertex. As the volume of a cube is the third power of its sides ‚ third powers are called cubes‚ by analogy with squares and second powers. A cube has the largest volume among cuboids (rectangular boxes) with a given surface area. Also‚ a cube has the largest volume among cuboids with the same total linear size (length+width+height). * Parts:

a better knowledge with the laboratory tools and techniques. This experiment taught me how to convert between SI units and standard American units of mass‚ length‚ temperature‚ volume and time as well as how to measure the units. Students become proficient in laboratory techniques such as measuring temperature and volume and calculating within them. Procedure: I used a measuring device such as a ruler‚ balance or volumetric flask to determine the values for each measurement. DATA Tables: Data Table

Tony Nguyen Honors Chemistry Period 7 9/17/13 The Density of Metals Lab BACKROUND: Density is a constant relationship between the mass and volume of a specific type of matter. Measurements of both mass and volume can be obtained for a metal sample. The relationship can be shown graphically by plotting the volume of a sample on the horizontal x-axis and the mass of the sample along the vertical y-axis. Plotting the values for several samples‚ a linear relationship can be seen for a density (slope=density)

Constant Density: Displacement of Zinc and Tin Introduction: Density is the concentration of molecules within an object on relation to its size. The formula for measuring density is mass/volume. In the experiment preformed for this lab report‚ calculating the density of a regular object (a wooden block) and two other irregular objects (zinc and tin) were found by a process known as water displacement. The purpose of this experiment was to prove that the density of an object remains the same
