Irregularly shaped solid

The density of an irregularly shaped solid is usually determined by measuring the mass and then measuring the volume of liquid that it displaces. The volume of liquid in a graduated cylinder is measured before the object is submerged and then measured again with the object submerged. The difference in the volume equals the volume of the object. 

Can be used to find the mass of an irregularly shaped solid. 

D By placing an irregularly shaped solid into a graduated cylinder with a known volume of water, the water is displaced by a certain volume. If the density of the solid is known, then the mass of the object can be calculated. If the mass of the solid is known, then the density of the object can be calculated. 

To illustrate this method, we will consider the determination of the density of an irregularly shaped solid. In this determination we make three measurements. First, we measure the mass of the object on a balance. Next, we must obtain the volume of the solid. The easiest method for doing this is to partially fill a graduated cylinder with a liquid and record the volume. Then we add the solid and record the volume again. The difference in the measured... 

The addition of irregularly shaped solids always gives a higher viscosity than smooth spherical solids. 

Explain how you might determine the identity of an irregularly shaped solid that is soluble in water. 

Raman Spectroscopy. As mentioned earlier, the Raman effect is an emission phenomenon, which means that front-surface sampling is possible. An irregularly shaped solid may be used in the spectrometer without processing it to make it flat, as required for internal reflection, or without processing it to a film or powder for transmission IR. Another sampling convenience is that Raman is more easily applicable to water solutions than IR. 

Problem The volume of an irregularly shaped solid can be determined from the volume of water it displaces. A graduated cylinder contains 19.9 mL of water. When a small piece of galena, an ore of lead, is added, it sinks and the volume increases to 24.5 mL. What is the volume of the piece of galena in cm and in L ... 

In fact, the derived SI unit for volume is the cubic meter. It is easy to visualize a cubic meter imagine a large cube whose sides are each 1 m in length. The volume of an irregularly shaped solid can be determined using the water displacement method, a method used in the MiniLab in this section. 

What is the density of an unknown and irregularly shaped solid To calculate the density of an object, you need to know its mass and volume. 

The volume of an irregularly shaped solid can be determined by measuring the amount of water it displaces. 

Although most solids are not spherical in shape, the sphere is the point of reference for the analysis of irregularly shaped solids. 

Irregularly shaped solids do not have regular dimensions and therefore cannot have their volumes calculated with a formula. Rather, we determine their volumes by water displacement (assuming that they do not dissolve in water). This means that the volume of water a solid displaces upon complete immersion is equal to the volume of the solid. In the laboratory, the process is as follows ... 

Given the following data for an irregularly shaped solid, what is the object s density ... 

For irregularly shaped solids, the standard correlations such as the Wen and Yu correlation [20] should only be used to give a rough approximation of the minimum fluidization velocity. Instead the use of measured values of the particle shape factor and of the voidage at minimum fluidization conditions in equation (5) is recommended.

EXAMPLE 1-3 Determining the Density of an Irregularly Shaped Solid... 

When submerged in a liquid, an irregularly shaped solid displaces a volume of liquid equal to its own volume. The necessary data can be obtained by two mass measurements of the type illustrated here the required calculations are like those in Example 1-3.
