convertion of one scale into another F 212°F RiF 32°F / Ric 100°C i R2-32 - 212-32 = R1-0 100-0 R2-32 R1-0 = 212-32 100-0

R, : one scale (known) R2: other scale Cunkno. wn). R2 - L.F.P RI-LFP = UFP-LFP UFP-LFP slope of the graph: slope = 212-32 100-0 = 100 =9/5 180 Intercept = tve=32 Xintercept --ve ? 3°c into F ? ans: R1=30°C R2-? R2-32 30-0 = 212-32 100-0 R2-32 =30 180 100 R2-32 - 3X13 R2=54+32 R2 = 86°F
