What is the process that happens when a liquid cools to a solid? For an adiabatic reversible expansion, which of the following statement is correct? Explain your answer: A) \Delta S_{sys} = \Delta S_{sourr} = \Delta S_{total} = 0 B) \Delta S_{sys} = \Delta S_{sourr} = ...
this happens when the particles are so saturated with energy that the only place they can go is into higher energy states, not lower. the particle velocity distribution for a regular hot gas would show that most particles are found towards the colder temperature...
Benzoic acid and acetanilide are sparingly soluble in cold water but soluble in hot water, hence the choice of water as a crystallization solvent. Explain. When an aqueous solution is cooled to low temperatures, part of the water freezes as pur...
Asking about speed is a very interesting question. You might as a "normal human being" think that if I measure the polarization of one photon, that sets the state of the other photon. That thinking is fine, as long as the other photon measurement happensafterthe first measurement. But ther...
Uranium in a nuclear reactor produces heat when it splits, or fissions, which is what happens when a fragile uranium -235 (U-235) atomic nucleus is hit by a neutron. At the same time, fission produces several neutrons that can go on to cause yet more fissions, providing a smooth, st...
QWhat happens if I press the AC button while the car is already cool? A If you press the AC button while the car is already cool, the system will continue to maintain the set temperature and airflow. The AC button allows you to adjust the cooling settings as needed, ensuring that you...
Because they are radioactive, radon and radon progeny emit alpha particles, a high-energy radiation that damages DNA in human cells and causes lung cancer. When radon is inhaled, particles become lodged in the lungs where they continue to emit alpha particles. ...
To start, let's look at what happens when lava moves over a proxy organic material: vegetation. According to the United States Geological Survey (USGS), lava coming from Mount Kilauea, for example, has a temperature of roughly 1,150 degrees Celsius (or 2,100 degrees Fahrenheit). That's ...
For some fields (such as the photon field and Z field) these particle and anti-particle ripples are actually the same thing; but for fields like electrons and quarks, the particles and anti-particles are quite different. So what happens when the electron field is disturbed by a passing ...
200° C. The hot gases released in volcanic eruptions include carbon dioxide, sulfur dioxide, nitrogen, argon, methane, and carbon monoxide, as well as water vapor. Ash, which can be as small as dust particles and large as rocks and pebbles, is made of cooled rock ...
