ahg i see.

thats the problem. my coices are 400, 100, 200, 1600 and none of the above. and i answered none the above, but answer is 1600.

The answer was 1600..?

Homework Statement the latent heat of fusion for this metal is 500Cal/kg. The latent heat of vaporization is 600Cal/kg and specific heat of the liquid metal is 500C/kg K. How much heat is needed to melt an 8kg block of this metal when its temperature is exactly at the melting point...

Homework Statement ^--------------^ |..../ |.../ |.../ |.../ |.../ |.../ |/_____________> ignore the dots If my y component is 120m/s and my X component is 50m/s, how do I go about finding initial V?? Attempt: i know that the y component = sin(O)*V and the x= cos (O) *V...

bummer. I think i might just have to guess on this one.

I keep examining what u wrote about temp going down means volume and/or pressure goes down. What if pressure is Dropped and Volume is INcreased?? then the temp will stay the same if they are decreased and increased by an even amount? Ex: if Pressure is dropped by say, 1/3rd and Volume is...

or perhaps the molar mass of nitrogen is wrong? i searched google and see that 14.01g/mol is molarmass of nitrogen..

not an answer. either.

see that's where my concepts are all messed up.. Because when I try to get a feel for it i think of V/T and I think that if temp gets smaller, the volume has to increase to keep the ratios the same. but now that you mention, if you cool a balloon by 100K, the Volume will DEFINITLY decrease to...

so it would be 4:3. since the volume of first temp would be less than of second? (since the Temp Values and they have to even out?)

wow. gniel. thanks so much! KELVING temps. duurrrh

the dividing part wouldn't work. (physically) but the ratio would be 0:100 or 100:0 ?

no i don't think it would.. (?)

oh yes perhaps. let me see... so gauge pressure means 1atm+2.5 atm= 354637.5 *.2 = 70927.5 / (8.31*573.15) = 14.89Do you think i should contact my teacher? perhaps maybe the solutionn isn't an option?
