WebbThe Fahrenheit scale (/ ˈ f æ r ə n ˌ h aɪ t, ˈ f ɑː r-/) is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit.Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was … WebbThe pH scale, which measures from 0 to 14, provides an indication of just how acidic or basic a substance is. Most parts of our body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). If foreign strong substances dramatically change this pH, our bodies can no longer function properly. WebbThe concentration of hydrogen ions can vary across many orders of magnitude—from 1 to 0.00000000000001 moles per liter—and we express acidity on a logarithmic scale called the pH scale. Because the pH scale is logarithmic (pH = -log [H + ]), a change of one pH unit corresponds to a ten-fold change in hydrogen ion concentration (Figure 1). city bank norge
