The temperature of the Suns interior is about 107 degrees. Does it matter whether this is degrees Celsius or kelvins? Defend your answer. No, it DOESNt matter whether this is in degrees Celsius or kelvins, since the DIFFERENCE between these scales is ONLY 273 of either measure, and that is ABSOLUTELY negligible w.r.t. the magnitude of the number 107. However, what is more important, perhaps, is that your value of 107 is itself a rather loose characterization. Modernsolar evolutionary models suggest rather that the Suns T_c is 1.5 x 107 (degrees Celsius or kelvins) or else of merely 107. (Our understanding of solar physics is certainly such that an error of a ingredient of 1.5 in its central temperature would be considered way out of all reasonable possibility) Of course the mathematical factor in front of 107 would matter even more if one were using the (non-scientific) Fahrenheit scale. Once again, however (unlike National Geographic magazine, which should hang its head in shame everyplace some of its conversions), one would NOT say that the Suns central temperature was about 2.7 x 107 and 32 degrees Fahrenheit 2. What happens to the attack cart within a sealed gallon can when it is heated? Cooled? why? The gases in general obey the gas laws. As per the law the draw,volume and temperature of the gas is related as P1V/T1 =P2V2/T2WhereP1 is pressure at stage 1, V1 is volume at stage 1 and T1 is temperature (Kelvin) for stage 1,and P2,V2 and T2 are the pressure,volume and temperature for stage 2. Now, if a gas contained in a sealed gallon is heatedor cooled the volume of the gas is constant but pressure and temperature will adjust u=in such a way that the P1/T1 =P2/T2If T2 is more than T1,then( heating the gas )P2= P1*T2/T1as T2 T1 so P2 will bve more than P1,hence, the pressure will incre ase. If T2
