Answer 1

ANSWER:

I KEPT U A DERIVATION , ITS FROM THE CHAPTER 'THERMAL PROPERTIES OF MATTER'

IF U CAN'T UNDERSTAND THE DERIVATION JUST FOLLOW LAST FORUMULA

U CAN FIND THE ALPHA VALUE BY SUBSTITUTING THE VALUES T1,T2 AS GIVEN IN QUESTION ie.30°,570°

After finding ALPHA value u can find the RESISTANCE R2 BY SUBSTITUTING T2 AS 240° AND T1,R1 AS GIVEN IN QUESTION
