Why can liquid boil at a low pressure?
Reducing the air pressure allows the molecules to escape
What is nuclear fuel made of?
A fuel rod is a metal tube (zirconium alloy) that contains fuel pellets in bundles (stacks). Fuel pellets vary in composition, but most consist of uranium and/or plutonium in some form. One type is uranium dioxide powder that has been compressed and heated to form a ceramic. Zirconium is used as a container because it has low neutron absorption, and allows the neutron radiation being produced by the fuel to escape into the surrounding reactor core so it can do its work of heating water to make steam that drives the power plant turbines. The size of a fuel rod depends on the type of fuel and the application. A CANDU fuel rod, for example, may be 50 cm long and 10 cm in diameter.
Why does the water freeze when a beaker of ether is placed over the water?
Because ether is much more volatile than water and evaporates extremely quickly. As ether evaporates very quickly its average kinetic energy is lowered as molecules of ether escape. Following on, the 2nd law of Thermodynamics (I think) states that thermal energy is lost to cooler things so the water cools down extremely quickly as it looses heat to the evaporating ether which is also loosing heat in evaporation. Once the water reaches 0 degrees C it freezes.
What factors affect the vapour pressure of a liquid?
Vapor pressure or equilibrium vapor pressure are the pressure of a vapor in thermodynamic equilibrium with its condensed phases in a closed bottle. All liquids and solids have a tendency to evaporate into a gaseous form, and all gases have a tendency to condense back to their liquid or solid form.The equilibrium vapour pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapour pressure at normal temperatures is often referred to as volatile
When bubble of gas form in a liquid escape what is this called?
condensation
Dense core formed after the explosions of a red giant?
neutron star If the star has low mass it will form a White Dwarf If Large enough it will explode (supernova) into a Neutron star (Extremely dense. Roughly 4x107kg m-3) which rotates up to 600 times per seconds causing the emission of Pulsars. It can then collapse further to create black holes which are so dense light can't escape their surface as they warp Spacetime by massive amounts
What is so small and massive that it's gravity does not let light escape?
A black hole because it can be small and massive and not even light can escape it.
What is so small and massive that it's gravity does not even let light escape?
A black hole because it can be small and massive and not even light can escape it.
How is a neutron star different from a black hole?
A neutron star is the collapsed core of a star in which atoms have been crushed, and electrons have fused with protons to form neutrons. The collapse stops at this point. A neutron star is extremely dense but has a finite density and emits radiation. A black hole is an object that has collapsed completely to an infinitely dense point. It cannot really be considered matter at this point. Around this singularity is a region of extremely strong gravity and highly distorted spacetime from which nothing, not even light can escape.
What is so massive that its gravity does not let light escape?
A black hole.
How are black hole different from neutron star?
A neutron star is an extremely dense object in which atoms have been crushed by gravity, causing electrons and protons to merge into neutrons. A force known as neutron degeneracy pressure prevents it from collapsing further. The neutron star can emit light and other forms of radiation. A black hole is an object that has completely collapsed under the force of gravity, with all mass coming to a single point called a singularity. The gravity is so strong that, within a certain radius nothing, not even light, can escape.
What are the names of the people that escape from adolf Hitler?
Extremely Lucky.
What is an object so massive that light cannot escape its gravity called?
A black hole
Is so massive that its gravity does not even let light escape?
That would be a black hole.
How do you escape Juji-Gatame?
Call in a massive aerial attack and hopefully you can get out of the prison unnoticed.
What is another name for black holes?
When a very massive star dies in a supernova explosion, a good fraction of its mass is (we believe) crushed into an extremely dense mass. The surface gravity of such a mass is so great that not even light can escape. Because no light can escape, physicists called it a "black hole in space".Because no light can escape, it can never be directly observed, but we are able to detect a black hole by the motions of other stars and the gas and debris around the shattered star remnant.
The more massive is an object and the smaller is its radius the greater or smaller is the escape velocity from it?
For two bodies with equal radius, the more massive has the greater escape velocity. For two bodies with equal mass, the one with smaller radius has the greater escape velocity. Both conditions listed in the question indicate greaterescape velocity.
