pH Scale

79.8K
Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Scaling

In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

Thermometers and Temperature Scales

7.6K
Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation.
As many physical properties depend on temperature, the variety of thermometers is...

Gas Thermometers and the Kelvin Scale

6.3K
The definition of temperature in terms of molecular motion suggests that there should be a lowest possible temperature, where the average kinetic energy of molecules is zero (or the minimum allowed by quantum mechanics). Experiments confirm the existence of such a temperature, called absolute zero. An absolute temperature scale is one whose zero point is absolute zero. Such scales are convenient in science because several physical quantities, such as the volume of an ideal gas, are directly...

Surveys

16.8K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

pH

The potential of hydrogen (pH) is a measure of the acidity or basicity of a water-based solution determined by the concentration of hydronium ions (H3O+). In one liter of pure water at neutral pH, there are 1×10−7 moles of hydronium ions. However, the extensive range of hydronium ion concentrations present in water-based solutions makes measuring pH in moles cumbersome. Therefore, a pH scale was developed to convert moles of hydronium ions into the negative logarithm of the hydronium...

Area of Science:

  • Social Sciences
  • Communication Studies
  • Psychology

Background:

  • Twitter facilitates rapid information spread, influencing user attitudes and behaviors.
  • Understanding retweeting provides insights into online network organization and public discourse.
  • Retweeting is crucial for public health, policy, disaster management, and civic engagement.

Purpose of the Study:

  • To conceptualize and validate the Why We Retweet Scale.
  • To assess the underlying motivations driving users to retweet content.
  • To provide a measurable framework for understanding information propagation on social media.

Main Methods:

  • A survey of 1433 Twitter users was conducted to gather data on retweeting behaviors.
  • Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were employed for scale development and validation.
  • Statistical analyses, including ANOVA and t-tests, examined demographic differences in retweeting motivations.

Main Results:

  • A 9-item, 4-factor scale, the Why We Retweet Scale, was validated.
  • The identified factors are: Show approval, Argue, Gain attention, and Entertain.
  • The scale demonstrated a parsimonious and reliable structure for measuring retweeting motivations.

Conclusions:

  • The Why We Retweet Scale offers a robust tool for assessing motivations behind retweeting.
