Can cryonics work if you use pressure rather than
It is also my understanding that water can be frozen by changing pressure rather than temperature. Since pressure can be increased extremely rapidly (at the speed of sound [which can be manipulated by pressure] or even faster via shockwaves), it would seem that freezing a person by pressure could potentially be extremely rapid.

Speed of sound in air vs. helium UCSB
Since the speed, frequency and length of a sound wave are related by the equation ν = v/λ, the frequency of a sound produced by a resonator of a particular length is proportional to the speed of sound in the particular gas that fills the resonator. This is why when you inhale helium from a balloon, the pitch of your voice rises so dramatically. Since the speed of sound in helium is almost

: The Rate of a Chemical Reaction
Effect of Concentration on Rate of Reaction. If you had an enclosed space, like a classroom, and there was one red ball and one green ball flying around the room with random motion and undergoing perfectly elastic collisions with the walls and with each other, in a given amount of time, the balls would collide with each other a certain number of times determined by probability.

Why Does Canned Air Get Cold? | Sciencing
Canned air is a common tool used for working on computers and general electronics. The strong puffs of air are handy for removing dust from the mouse and keyboard, monitors, fans and other equipment. If you have used canned air, you''ve noticed the peculiar reaction that occurs: the can gets cold and, in some cases, frost forms on the can and the straw attached to the nozzle.

Frequency Coding in the Nervous System
Physiologically, action potential frequencies of up to 200300 per second (Hz) are routinely observed. Higher frequencies are also observed, but the maximum frequency is ultimately limited by the absolute refractory period. Because the absolute refractory period is ~1 ms, there is a limit to the highest frequency at which neurons can respond to strong stimuli. That is to say that the absolute

Choosing The Right Shocks The Ranger Station
These are highpressure gas shocks with only one tube, the pressure tube. Inside the pressure tube there are two pistons: a dividing piston and a working piston. The working piston and rod are very similar to the twin tube shock design. The difference in actual application is that a monotube shock absorber can be mounted upside down or right side up and will work either way. In addition to

The higher the rms speed of air molecules, the faster sound vibrations can be transferred through the air. The speed of sound increases with temperature and is greater in gases with small molecular masses, such as helium (see Figure ).

The equation of state and heat capacity of nitrogen have been determined at temperatures from K to K and at pressures from 200 MPa to 1000 MPa using a new computational method. This is based on stepwise construction of p ( T ) isochores starting from an experimental reference p ( ρ ) isotherm and using the previously reported speeds of sound of nitrogen as a function of pressure

While larger mobile crushers produce more aggregate faster, transport weights and dimensions may limit how easily the crusher can be shipped long distances. Mobile jaw crushers can have either a vibratory feeder with integrated grizzly, or a vibrating feeder with an independent, doubledeck, heavyduty prescreen. Either way, wear in the system is reduced because medium and smaller gradations

Nitrogen | N2 PubChem
Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78% by volume of Earth''s atmosphere. Nitrogen occurs in all living organisms. It is a constituent element of amino acids and therefore of proteins and nucleic acids (DNA and RNA). Nitrogen is found in the chemical structure of almost all neurotransmitters and is a key

resonance What is the resonant frequency of
What is important in the idea of resonance with water is to establish a frequency of excitation that causes the natural frequencies to superimpose or wave superposition. By achieving wave superposition the amplitude of the oscillations will have the greatest potential of breaking the molecule into its elemental constituents thereby creating free atoms that can recombine to form the diatomic
