Determine the specific heat of a material if a 22 g sample of the material absorbs 41 J as it is heated from 298 K to 313 K?
It can be written as 41/(15*22) joules/g*K
Determine the specific heat of a material if a 35 g sample of the material absorbs 48 J as it is heated from 298 K to 313 K?
Some materials have multiple solid phases, others do not. It depends on the particular material and also on the temperature and pressure conditions. If you want to know what phases a specific material at a particular pressure goes through as it is heated from temperature X to temperature Y, that would be answerable by looking at a phase diagram for that material, but the generic form cannot be answered.
The main advantage of thermoplastic material is that it can be heated up, molded and then cooled again with no changes to the overall properties of the material (like it getting weaker and falling apart, for instance). Thermoplastics can be re-heated and re-molded as well, which is in contrast to thermosetting materials which can be heated and molded once but then not reset.
A 0.050g ball of aluminum foil absorbs 1.42 heat when it is heated 31.6C What is the specific heat of aluminum foil?
In a beaker sugar is dissolved in water and then the water is heated and evaporates The sugar is recovered and heat is again applied Vapor is released and the material in the beaker changes from?
In a beaker, sugar is dissolved in water, and then the water is heated and evaporates. The sugar is recovered, and heat is again applied. Vapor is released, and the material in the beaker changes from white to black. What must you know to determine if a chemical change occurred? CO2 (carbon dioxide) CuO (oxidized copper) H2O (distilled water) H2O2 (hydrogen peroxide) NaCl (sodium chloride)
The heating of a solid body, which absorbs radiant energy, was studied. With sufficient radiantenergy flow, the surface of the body can achieve such a high temperature that the physiochemical conversions of the material are unavoidable. Emphasis was placed upon the one-dimensional problem of the evaporation of the solid body, heated from the incident radiant energy. It is assumed that the flow of radiant energy is absorbed on the surface of the body and is…
