Open, Closed and Isolated Systems in Physical Chemistry

Suppose we have a system which is a drink in a glass. Certainly heat flows in and warms the cold drink, and mass changes when we add to the glass or drink the contents. The system is open.

Quantum Crackpot RANDI Challenge Taken: Part 2

An unfiltered particle is called “Pristine” as defined in the website called Bell’s theorem refuted. The values of the LHV of a pristine particle are unknown. A pristine EPR pair is one before filtering. ....I will present a model that shows a disentangled product state not only gives the quantum result, but predicts something new.

Understanding State Functions and Reversible Paths

First it is never possible to obtain a true reversible path. It is an idealized case in which at every step along the way the system (the ball) is in equilibrium with its surroundings. Clearly if something is at equilibrium there is no noticeable change. Hence one says that a reversible process happens so slowly that equilibrium is always maintained.

Quantum Crackpot RANDI Counter Challenge: “Explain Quantum Weirdness”.

The phrase “quantum weirdness” is recognized as meaningless and has no place in science.

Quantum Crackpot-a Challenge Taken

Their challenge is—“Anybody with some crackpot “local QM” theory is cordially invited to either write the program so that Bell’s inequality is violated or to shut the hell up!"

Nature has 2.71828… fingers

At a rate of 10% your money will double in 7 years . If you invest $1,000 in a tax free pension account at 10%, then after 35 years that $1,000 will have grown to $32,000!

The Chemical Kinetics of Sobering Up

The time to reduce 4 beers to 2 is two hours. The time to go from 2 beers to 1 is one hour, and the time to go from 1 beer to the legal limit is 30 minutes. It therefore takes a whooping 3.5 hours to reach the legal limit: 4 beers take seven times longer to metabolize than 1 beer.

The Thermodynamics of Weight Loss.

Another way to ask the same question: suppose you have eaten all the food you need to keep your metabolism and daily activity going, but then you have one cookie too many. How much fat will that put on you?

Cooking Chemistry: Recipe for Right Density Pancakes

Let us suppose that you read somewhere that perfect pancakes should have a density of 0.7 g ml-1. How could you ensure that you cook the pancakes so that they come out with that density?

Panting Hot Chickens, Carbon Dioxide and Carbonic Acid

What do hot chickens, pH of blood, bubbly drinks, coral reefs, and thermostating the Earth have in common? They all make use of one of the most basic processes in the Physical Chemistry: the equilibrium between carbon dioxide and carbonic acid.
