- Pink salmon — too much of a good thing? | Geophysical Institute
Pink salmon born in hatcheries, where professionals harvest eggs from wild salmon and rear them in captivity before releasing them in the ocean, have doubled in numbers since 1990 Russians have pink salmon hatcheries that increase numbers in the North Pacific and Bering Sea Alaskans run hatcheries in Valdez and other places in Prince William
- Why Does the Pink Color in a Titration Fade Over Time?
The discussion revolves around the fading of the pink color produced by phenolphthalein during a titration over time Participants explore various chemical processes and factors that may contribute to this phenomenon, including equilibrium shifts, hydrolysis, and the absorption of carbon dioxide
- Creating Pink Sterling Silver: Chemistry and Heat Treatment Explained
The discussion centers on methods to create a pink hue in sterling silver, exploring both chemical adjustments to the alloy and potential heat treatment techniques Participants consider the implications of alloy composition and surface treatments in achieving the desired coloration One participant inquires about altering the chemistry of sterling silver, which is typically 92 5% silver and 7
- Laptop screen flickering moving up and down with pink tint
The discussion revolves around a laptop screen issue characterized by flickering, movement up and down, and a pink tint Participants explore potential causes, including hardware and software problems, and share personal experiences related to similar issues The context includes troubleshooting steps and concerns about data privacy during potential repairs One participant describes the issue
- Understanding FTIR Peaks of PO4 Compounds • Physics Forums
The discussion focuses on the interpretation of FTIR (Fourier Transform Infrared Spectroscopy) peaks for PO4 (phosphate) compounds It establishes that multiple peaks at different wavelengths arise from various vibrational modes of the molecule, including stretching and bending vibrations Specifically, the modes v1, v3, and v4 correspond to distinct types of molecular vibrations, such as
- Why does a Walrus Blush? | Geophysical Institute
The skin of walruses becomes pallid when it is exposed to cold air or water and changes to pink when exposed to warmer ambient temperatures This color change may indicate that the circulatory output to the skin is altered to control their total body heat loss
- Exploration into the Physics of Rainbows
The simplest explanation of rainbow physics is based on internal reflections in the near-spherical shape of a raindrop
- What do the blue and pink color of the rust indicator shown mean?
The discussion revolves around the interpretation of color changes in a rust indicator composed of potassium hexacyanoferrate (III) and phenolphthalein when applied to an iron nail Participants explore the significance of blue and pink colors observed in different regions of the nail, questioning what these colors indicate about the presence of specific ions and the rusting process Some
