I think we need to know coeffecient of resistance to solve this question. The formula used would be. See the page --> http://www.rdfcorp.com/anotes/pa-rtd/pa-rtd_02.shtml

Or Resistance at 100 degree C .  Anyone would help.
t= ( (R_t - R_0) / (R_100 - R_0) ) * 100
R_t-->resistance at temp t 
R_0 --> resistance at temp 0 degree C
R_100 ->resistance at temp  100 degree C

i think the answer is 141 degrees----- if 152E at 273k then 230.51 is 141

Yes maybe.  It maybe simple ratio and proportion sum :)
