When a solid(固体)is heated to reach itsmelting point(熔点),it will change into aliquid.This is a(n)l.(结论)that weall know,because we have seen how ice melts.For a solid to change into a liquid state,theparticles(粒子)in the solid need to be freedfrom their fixed places.How ...
When there is a change in the temperature of the body then at the molecular level there will be a change in the dimension of the object and generally when the substance is heated then the kinetic energy of the molecules of the substance is increased w...
Describe what occurs to the particles of a substance when the 1-tetradecanol melts. Explain why this occurs. How does the climate system connect with carbon dioxide? What happens when lightning strikes the ground? How does the carbon cycle affect the ocean? What is causing the melting of the...
An allergy (过敏反应) is a strong reaction to a substance. Many things can cause allergies. The most common cause is pollen (花粉) which is usually produced by trees in the spring grasses in the summer and weeds in the fall as part of their reproductive process. Other causes include orga...

Heating a substance can change the void size depending on the effect heating has on the material due to crystallization and other effects which will affect the porosity and obviously the rate of any minute or substantial amounts of fluids that could excrete or pour through a given material used...
FIELD: metallurgy.;SUBSTANCE: solid slag is supplied from taphole to vacuum furnace during coal firing so that molten slag and gaseous oxides are obtained and removed from the furnace for further processing. Molten slag is tapped to ladle, blown with heated air and supplied to a centrifuge for...
the formation of heavier nuclei is also possible when the nuclear reaction proceeds with the absorption of excess energy. This is how the substance that makes up our planet was formed, including a small amount of uranium, which we extract and burn in nuclear power plants. It is believed that...
In the fused acidolysis process or the slurry polymerization process, whichever may be chosen, the organic monomeric reactive substance from which the aromatic polyester is derived can be used for the reaction in the modified form in which the hydroxyl group of the monomer is esterified (or in ...
