Answer: Friction is a force that resists relative motion between two surfaces in contact. Depending on the application, friction may be desirable or undesirable.
The average kinetic energy of 1 mole of a gas at -32 degrees Celsius is:
3.80 x 103 J
The relationship between volume and temperature of a gas, when pressure and moles of a gas are held constant, is: V*T = k.
FALSE
The relationship between moles and volume, when pressure and temperature of a gas are held constant, is: V/n = k. We could say then, that:
If the moles of gas are tripled, the volume must also triple.
If the temperature and volume of a gas are held constant, an increase in pressure would most likely be caused by an increase in the number of moles of gas.
TRUE
If the vapor pressure of a liquid is less than the atmospheric pressure, the liquid will not boil.
TRUE

Answer:
The correct answer is option B
B. In a sample of enriched uranium
Explanation:
Nuclear fission is a nuclear reaction whereby large nucleus of an atom is break down into smaller parts lighter nuclei or daughter nuclei and release large amount of energy, due to the large amount of energy there are alot of heat released.
During the process large nucleous is bombarded by the neutrons, as a result of this the nucleous becomes disintegrated because it's unstable and their is production of lighter nuclei as well as neutrons and energy.
When the U -235 particles are compacted together there result a high energy neutron which can bombard another Uranium - 235 molecule in the region. uranium is enriched with more of the fissile uranium isotope, then when it is enriched it can be used to make atomic reactors and explosives like bombs.
Answer:
if im not mistaken that's a jetstream
