Quick serial number guide:No serial number, pre 1967 riflesSerial number range 400-419K 1967 rifleSerial number range 419-473K 1968 rifleSerial number range 2.1 million-2.59 million December 1968- January 1977 rifleSerial number range with an "A" prefix-post Feb 1977 rifle.
Is heat emitted by the body at 200 celsius is twice the heat emitted by the body at 100 celsius?
Not at all. First of all, 200 Celsius is not double 100 Celsius. To make this kind of comparisons, you have to use an absolute scale, i.e., Kelvin. 200 Celsius = 473K; 100 Celsius = 373K, so that is only about a 27% increase. Second, the energy emitted by a hot body is (roughly?) proportional to the 4th. power of the temperature. Raising the ratio to the fourth power gives you a factor of about 2.59 - the hotter body will radiate 2.59 times as much heat energy as the cooler body.
How do you convert aniline to phenol?
Use acetic anhydride as reagent. The reaction will undergo nucleophilic addition and the reagent will attach to the amine group. Half of the reagent will become the leaving group and one H of the amine group in the reactant will leave with the reagent. The product will be the benzene ring with an amine, carbonyl, methyl attached.
How much heat engery is required to raise the temperature of 5 kilograms of coal from 20 c to220 c?
The amount of heat energy (q) gained or lost by a substance is equal to the mass of the substance (m) multiplied by its specific heat capacity (Cg) multiplied by the change in temperature (final temperature - initial temperature) q = m x Cg x (Tf - Ti)q is what we are finding.m of coal = 5 kgCg of coal (anthracite) = 1.38 kJ/kg-K (kilojoules per kilogram-Kelvin)Tf = 220 °C.Ti = 20 °C.using the data above.q = m x Cg x (Tf - Ti)q = 5 x 1.38 x (220 - 20) -- temperature change same in K or °Cq = 5 x 1.38 x 200q = 1380 kilo-joules(kj) or 1.3 x 106 joules---The formula isQ=m*c*(T2-T1)Energy=mass*specific heat capacity*( temperature higher - temperature lower)(assuming the volume of your substance doesn't change during the heating)Energy Required = Mass x "Specific Heat Capacity" x Temperature changeFor anthracite coal, the specific heat is 1.38 kJ / kgK , yielding E = 1.38 (5kg)(200K) = 1380 kJ.
