How to Measure the Volume of a Solid Object By Chris Deziel; Updated April 29, If you have an object with a standard geometric shape, such as a cube or a sphere, you can calculate its volume by measuring its dimensions and using the relevant mathematical formula. For example, if you measure the length of one side of a cube Lthe volume of the cube is L3.
Overview Modern philosophical discussions about measurement—spanning from the late nineteenth century to the present day—may be divided into several strands of scholarship.
These strands reflect different perspectives on the nature of measurement and the conditions that make measurement possible and reliable. The main strands are mathematical theories of measurement, operationalism, conventionalism, realism, information-theoretic accounts and model-based accounts.
These strands of scholarship do not, for the most part, constitute directly competing views. Instead, they are best understood as highlighting different and complementary aspects of measurement. The following is a very rough overview of these perspectives: Mathematical theories of measurement view measurement as the mapping of qualitative empirical relations to relations among numbers or other mathematical entities.
Information-theoretic accounts view measurement as the gathering and interpretation of information about a system. These perspectives are in principle consistent with each other.
While mathematical theories of measurement deal with the mathematical foundations of measurement scales, operationalism and conventionalism are primarily concerned with the semantics of quantity terms, realism is concerned with the metaphysical status of measurable quantities, and information-theoretic and model-based accounts are concerned with the epistemological aspects of measuring.
Nonetheless, the subject domain is not as neatly divided as the list above suggests. Issues concerning the metaphysics, epistemology, semantics and mathematical foundations of measurement are interconnected and often bear on one another.
Hence, for example, operationalists and conventionalists have often adopted anti-realist views, and proponents of model-based accounts have argued against the prevailing empiricist interpretation of mathematical theories of measurement.
These subtleties will become clear in the following discussion. The list of strands of scholarship is neither exclusive nor exhaustive. It reflects the historical trajectory of the philosophical discussion thus far, rather than any principled distinction among different levels of analysis of measurement.
Some philosophical works on measurement belong to more than one strand, while many other works do not squarely fit either.
This is especially the case since the early s, when measurement returned to the forefront of philosophical discussion after several decades of relative neglect. The last section of this entry will be dedicated to surveying some of these developments.
The volume of a container is generally understood to be the capacity of the container, i. e. the amount of fluid (gas or liquid) that the container could hold, rather than the amount of . Measurements in the Laboratory Objectives The objectives of this laboratory are: a) Use standard laboratory measurement devices to measure length, volume and Volume is the amount of space occupied by matter. An extensive property is one that is dependent on the amount of matter present. Volume is an extensive property. For regularly. List of measuring devices. Device Quantity measured; accelerometer: physical, accelerations actinometer: volume and density of solids geiger counter: ionizing radiation (alpha, beta, gamma, etc.) glucometer: a spoon used to measure an amount of an ingredient, either liquid or dry megger: electrical insulation.
A Brief History Although the philosophy of measurement formed as a distinct area of inquiry only during the second half of the nineteenth century, fundamental concepts of measurement such as magnitude and quantity have been discussed since antiquity. Two magnitudes have a common measure when they are both whole multiples of some magnitude, and are incommensurable otherwise Book X, def.
The discovery of incommensurable magnitudes allowed Euclid and his contemporaries to develop the notion of a ratio of magnitudes.
Ratios can be either rational or irrational, and therefore the concept of ratio is more general than that of measure Michell; Grattan-Guinness Aristotle distinguished between quantities and qualities. Aristotle did not clearly specify whether degrees of qualities such as paleness correspond to distinct qualities, or whether the same quality, paleness, was capable of different intensities.
This topic was at the center of an ongoing debate in the thirteenth and fourteenth centuries Jung This theory was later refined by Nicole Oresme, who used geometrical figures to represent changes in the intensity of qualities such as velocity Clagett ; Sylla These developments made possible the formulation of quantitative laws of motion during the sixteenth and seventeenth centuries Grant The concept of qualitative intensity was further developed by Leibniz and Kant.
Leibniz argued that this principle applies not only to changes in extended magnitudes such as length and duration, but also to intensities of representational states of consciousness, such as sounds Jorgensen ; Diehl An example is length: For Kant, the possibility of such synthesis was grounded in the forms of intuition, namely space and time.
Intensive magnitudes, like warmth or colors, also come in continuous degrees, but their apprehension takes place in an instant rather than through a successive synthesis of parts. Scientific developments during the nineteenth century challenged the distinction between extensive and intensive magnitudes.
Thermodynamics and wave optics showed that differences in temperature and hue corresponded to differences in spatio-temporal magnitudes such as velocity and wavelength. Electrical magnitudes such as resistance and conductance were shown to be capable of addition and division despite not being extensive in the Kantian sense, i.
For example, 60 is twice 30, but one would be mistaken in thinking that an object measured at 60 degrees Celsius is twice as hot as an object at 30 degrees Celsius. This is because the zero point of the Celsius scale is arbitrary and does not correspond to an absence of temperature.
When subjects are asked to rank on a scale from 1 to 7 how strongly they agree with a given statement, there is no prima facie reason to think that the intervals between 5 and 6 and between 6 and 7 correspond to equal increments of strength of opinion.
These examples suggest that not all of the mathematical relations among numbers used in measurement are empirically significant, and that different kinds of measurement scale convey different kinds of empirically significant information. The study of measurement scales and the empirical information they convey is the main concern of mathematical theories of measurement.
A key insight of measurement theory is that the empirically significant aspects of a given mathematical structure are those that mirror relevant relations among the objects being measured. This mirroring, or mapping, of relations between objects and mathematical entities constitutes a measurement scale.Measuring Cups and Jugs.
Precise measurement is an essential part of baking, and often cooking in general. Whether it’s the right amount of liquids, flours or oils, whatever ingredients you’re working with, it’s nice to feel reassured that you’re getting the measurements right. If it says a cup of lettuce, that's volume, not weight.
I seriously doubt you'll be able to eat a half a pound of lettuce (8 ounces of weight), but a cup of lettuce is a reasonable portion (8 ounces of volume). How to Measure Carbon Dioxide Carbon dioxide measurement is required in many applications = amount of gas 2 [mol], etc.

JOHNSON CONTRIBUTIONS TO THE HYDROLOGY OF THE UNITED STATES For centuries, the amount of moisture in the soil has been of interest in agriculture.
The subject of soil moisture is also of great importance to the hydrologist, forester, and soils engineer. solids" coatings. Waterborne coatings, which have recently gained substantial use, are of several types: water emulsion, water soluble and colloidal dispersion, and electrocoat.
